The article was written by Prihed, Hagit; Shifrovich, Avital; Shamai Yamin, Tamar; Madmon, Moran; Smolkin, Boris; Chen, Ravit; Blanca, Merav; Weissberg, Avi. The article contains the following contents:

A new derivatization strategy for the detection and identification of sulfur mustard (HD) via liquid chromatog.-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) is developed. The method incorporates selective oxidation of the sulfide group by the electrophilic iodine reagent N-iodosuccinimide (NIS) to produce sulfur mustard monoxide (HDSO). The derivatization reaction efficiencies were evaluated with acetonitrile extracts of soil, asphalt, cloth, Formica, and linoleum spiked with HD at concentrations of 50-5000 pg/mL and found to be similar to that with pure acetonitrile. The current derivatization approach is the first to preserve the identity of chloride groups and support HD regulation and evidentiary findings. In the part of experimental materials, we found many familiar compounds, such as 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Category: iodides-buliding-blocks)

Zhang, Mingjing’s team published research in Polymers (Basel, Switzerland) in 2019 | CAS: 516-12-1

In 2019,Polymers (Basel, Switzerland) included an article by Zhang, Mingjing; Zhu, Liangjian; Guo, Pengzhi; Wang, Xunchang; Tong, Junfeng; Zhang, Xiaofang; Jia, Yongjian; Yang, Renqiang; Xia, Yangjun; Wang, Chenglong. Product Details of 516-12-1. The article was titled 《Effect of flank rotation on the photovoltaic properties of dithieno[2,3-d:2′,3′-d′]benzo [1,2-b:4,5-b′]dithiophene-based narrow band gap copolymers》. The information in the text is summarized as follows:

Side chain engineering has been an effective approach to modulate the solution processability, optoelectronic properties and miscibility of conjugated polymers (CPs) for organic/polymeric photovoltaic cells (PVCs). As compared with the most commonly used method of introducing alkyl chains, the employment of alkyl-substituted aryl flanks would provide two-dimensional (2-D) CPs having solution processability alongside addnl. merits like deepened HOMO (HOMO) energy levels, increased absorption coefficient and charger transporting, etc. In this paper, the triple C≃C bond was used as conjugated linker to decrease the steric hindrance between the flanks of 4,5-didecylthien-2-yl (T) and dithieno[2,3-d:2′,3′-d′]benzo[1,2-b:4,5-b′]dithiophene (DTBDT) core. In addition, an alternating CP derived from 4,5-didecylthien-2-yl-ethynyl (TE) flanked DTBDT, and 4,9-bis(4-octylthien-2-yl) naphtho[1,2-c:5,6-c′]bis[1,2,5]thiadiazole (DTNT), named as PDTBDT-TE-DTNT, was synthesized and characterized. As compared with the controlled PDTBDT-T-DTNT, which was derived from 4,5-didecylthien-2-yl flanked DTBDT and DTNT, the results for exciton dissociation probability, d. functional theory (DFT), time-resolved photoluminescence (PL) measurements, etc., revealed that the lower steric hindrance between TE and DTBDT might lead to the easier rotation of the TE flanks, thus contributing to the decrease of the exciton lifetime and dissociation probability, finally suppressing the short-circuit c.d. (JSC), etc., of the photovoltaic devices from PDTBDT-TE-DTNT. In the experimental materials used by the author, we found 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Product Details of 516-12-1)

Escopy, Samira’s team published research in Chemistry – A European Journal in 2021 | CAS: 516-12-1

Escopy, Samira; Singh, Yashapal; Stine, Keith J.; Demchenko, Alexei V. published their research in Chemistry – A European Journal in 2021. The article was titled 《A Streamlined Regenerative Glycosylation Reaction: Direct, Acid-Free Activation of Thioglycosides》.Synthetic Route of C4H4INO2 The article contains the following contents:

Our group has previously reported that 3,3-difluoroxindole (HOFox) is able to mediate glycosylation via intermediacy of OFox imidates. Thioglycoside precursors were first converted into the corresponding glycosyl bromides that were then converted into the OFox imidates in the presence of Ag2O followed by the activation with catalytic Lewis acid in a regenerative fashion. Reported herein is a direct conversion of thioglycosides via the regenerative approach that bypasses the intermediacy of bromides and eliminates the need for heavy-metal-based promoters. The direct regenerative activation of thioglycosides is achieved under neutral reaction conditions using only 1 equivalent NIS and catalytic HOFox without the acidic additives. In the experimental materials used by the author, we found 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Synthetic Route of C4H4INO2)

Manisha’s team published research in European Journal of Organic Chemistry in 2021 | CAS: 516-12-1

Manisha; Gupta, Shiv Shankar; Dhiman, Ankit Kumar; Sharma, Upendra published an article in 2021. The article was titled 《Rh(III)-Catalyzed Selective C7 Halogenation of Indolines》, and you may find the article in European Journal of Organic Chemistry.Application In Synthesis of 1-Iodopyrrolidine-2,5-dione The information in the text is summarized as follows:

An efficient Rh-catalyzed catalytic method has been developed for selective C7 halogenation of N-pyrimidyl indolines I (R = H, 5-Ph, 6-F, OCH2Ph, etc., R1 = H, 2-EtO2C, 3-Me, 2-Me, R2 = H) with N-halosuccinimides (halo = chloro, bromo, iodo) to produce the corresponding halides I (R2 = Br, Cl, I) in good to excellent yields. The advantages of this strategy include broad substrate scope and excellent regioselectivity for C7 functionalization of the indolines and feasibility at the gram scale level. Various control experiments have been performed to understand the reaction pathway. Applicability of current methodol. has been demonstrated by indole synthesis and post-transformation of the C7 halogenated indolines into different valuable mols. The reaction is also applicable to the preparation of halogenated carbazoles II (R2 = Br, Cl, I) and tetrahydroquinolines III (R2 = Br, I).

Musza, Katalin’s team published research in Journal of Molecular Structure in 2022 | CAS: 516-12-1

In 2022,Musza, Katalin; Meszaros, Rebeka; Baan, Kornelia; Konya, Zoltan; Kukovecz, Akos; Palinko, Istvan; Sipos, Pal; Szabados, Marton published an article in Journal of Molecular Structure. The title of the article was 《Mechanochemical preparation of NiCuSn nanoparticles and composites in presence of cetyltrimethylammonium bromide (CTAB) and the catalytic application of the products in homocoupling and hydration of terminal alkynes》.Related Products of 516-12-1 The author mentioned the following in the article:

The synthesis of the NiCuSn nanoparticles and nanocomposites in mechanochem. route using CTAB as milling additive was reported. The study of grinding intensity (frequency) and time interval drew up the importance of the well-chosen operation parameters. The mild milling resulted in formation of NiSn intermetallics, while the intense ones aided the evolution of bronze and copper(I) oxide phases. The utilization of CTAB proved to be the key factor to prevent or slow down the process of mech. alloying and to fritter the metal grains into the nanodimensions. The dynamic light scattering data demonstrated pos. charged particles with average solvodynamic diameters of around 70 nm applying intense or long-term millings. Without CTAB or with relatively short or weak grindings, these values remained between 230 and 550 nm, as in the case of the surface areas getting around 20 m2/g with and 1 m2/g without CTAB. The catalytic transformation of p-methoxyphenylacetylene in DMSO showed that the copper, copper(I) oxide and bronze particles managed the reaction toward the evolution of 1,3-diyne in Glaser-Hay homocoupling without base addition, while the Sn and SnO2 phases assisted to the Markovnikov-type hydration of alkyne groups. The formation of α-diketone signed that the anti-Markovnikov route was also occurred. The use of CTAB was found to exert a profound effect on the quality of catalytic end-products through the controlled generation of bronze and tin oxide phases and the solid solution of nickel atoms. In the part of experimental materials, we found many familiar compounds, such as 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Related Products of 516-12-1)

Ali, Basant A.’s team published research in Materials Today Communications in 2022 | CAS: 516-12-1

In 2022,Ali, Basant A.; Ahmed, Nashaat; Allam, Nageh K. published an article in Materials Today Communications. The title of the article was 《Deciphering the hype effect of Ni-foam substrate in electrochemical supercapacitors: Is there a way out》.Computed Properties of C4H4INO2 The author mentioned the following in the article:

Despite the subtle effects of the current collector on the overall supercapacitor performance, the substrate parasitic reactions have rarely been reported. Specifically, for the widely used Ni foam (Ni-F) current collector, the redox reaction of the Ni-F oxide layer is usually being confused with the true electrochem. signature of the active electrode materials. Herein, we studied electrodeposited MnS, CoS, and NiS active materials on two different substrates (Ni-F and carbon cloth (CC)). The study revealed that the sulfides deposited on Ni-F showed overestimated higher capacitance values than those deposited on CC. However, the retention and the rate capability were higher for those films deposited on CC. Furthermore, Ni-F was found to interfere with the redox reactions of MnS and CoS but not NiS. Moreover, Ni-F altered the charge storage mechanism of the electrodes. The results confirmed the interference of Ni-F with the deposited materials giving misleading primary results. On contrary, CC is an alternative high performance, flexible, and stable substrate. After reading the article, we found that the author used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Computed Properties of C4H4INO2)

Heller, Stephen T.’s team published research in Journal of Chemical Education in 2020 | CAS: 516-12-1

《The Value of Failure: A Student-Driven Course-Based Research Experience in an Undergraduate Organic Chemistry Lab Inspired by an Unexpected Result》 was written by Heller, Stephen T.; Duncan, Andrew P.; Moy, Cheryl L.; Kirk, Sarah R.. Application In Synthesis of 1-Iodopyrrolidine-2,5-dione And the article was included in Journal of Chemical Education in 2020. The article conveys some information:

Research experiences are widely understood to be valuable for the intellectual and professional development of undergraduate science students. Course-based undergraduate research experiences (CUREs) have become popular as a means of engaging large numbers of students in research by leveraging institutional supports for laboratory courses. At Willamette University, we have adapted a guided inquiry experiment that gave unexpected results into a CURE in the lower-division organic chem. curriculum. This experience has engaged several cohorts of students in a seven-week investigation focused on identifying the mechanistic origin of a nonstereospecific hydroxybromination of Z-stilbene, an observation that contradicts how this addition reaction is presented in standard organic chem. curricula. Each year, the cohort exptl. “”discovers”” the anomalous stereochem. outcome of the addition reaction. Over the next three lab sessions, students execute their experiments, reconsidering and revising their hypotheses as their data dictate. The experience culminates in formal oral and written presentations of results. Student perceptions of the pedagogical value of the CURE, the effect of the lab on their self-efficacy, and the novelty of research being conducted were assessed in multiple class cohorts, while faculty perceptions of changes in student behavior and skill were also documented. The experimental process involved the reaction of 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Application In Synthesis of 1-Iodopyrrolidine-2,5-dione)
