Catellani reactions of aryl iodides allow the double functionalization at the ortho and ipso positions in one pot. Catellani reactions involving a nitrene intermediate are not yet known. In this paper, a few palladium amino complexes were prepared from PdCl2, anthranil and iodoarenes, and their structures were determined by X-ray single-crystal diffraction. These complexes are supported by a pincer C,N,O tridentate ligand forming fused six-membered palladacycles. The high stability of the palladium complexes inhibits their reductive elimination.1-Iodonaphthalene(cas: 90-14-2Application In Synthesis of 1-Iodonaphthalene) was used in this study.

In 2019,Organic & Biomolecular Chemistry included an article by Li, Hongfang; Li, Tao; Hsueh, Yu Jen; Wu, Xue; Xu, Feng; Zhang, Yong Jian. Recommanded Product: 90-14-2. The article was titled 《Tandem arylation and regioselective allylic etherification of 2,3-allenol via Pd/B cooperative catalysis》. The information in the text is summarized as follows:

An efficient method for the construction of arylated allylic ethers ArC(=CH2)CH(OR)CH2OH (Ar = Ph, 2H-1,3-benzodioxol-5-yl, thiophen-2-yl, etc.; R = Et, Bn, cyclohexylmethyl, furan-2-ylmethyl, etc.) was developed via three-component tandem arylation and allylic etherification of 2,3-allenol with aryl iodides ArI and alcs ROH. In the cooperative catalytic system of a palladium complex and triethylborane, the process allows rapid access to functionalized 1-arylvinylated 1,2-diol derivatives in good to high yields with complete branch-selectivities. The synthetic utility of the present process was demonstrated by the late-stage functionalization of a drug mol., the gram-scale synthesis and the elaboration of the products. In the experiment, the researchers used many compounds, for example, 1-Iodonaphthalene(cas: 90-14-2Recommanded Product: 90-14-2)

《C14H10 polycyclic aromatic hydrocarbon formation by acetylene addition to naphthalenyl radicals observed》 was written by Yang, Jeehyun; Smith, Mica C.; Prendergast, Matthew B.; Chu, Te-Chun; Green, William H.. Synthetic Route of C10H7I And the article was included in Physical Chemistry Chemical Physics in 2021. The article conveys some information:

The formation of polycyclic aromatic hydrocarbons (PAHs) during combustion has a substantial impact on environmental pollution and public health. The hydrogen-abstraction-acetylene-addition (HACA) mechanism is expected to be a significant source of larger PAHs containing more than two rings. In this study, the reactions of 1-naphthalenyl and 2-naphthalenyl radicals with acetylene (C2H2) are investigated using VUV photoionization time-of-flight mass spectrometry at 500 to 800 K, 15 to 50 torr, and reaction times up to 10 ms. Our exptl. conditions allow us to probe the Bittner-Howard and modified Frenklach HACA routes, but not routes that require multiple radicals to drive the chem. The kinetic measurements are compared to a temperature-dependent kinetic model constructed using quantum chem. calculations and accounting for chem.-activation and fall-off effects. We measure significant quantities of C14H10 (likely phenanthrene and anthracene), as well as 2-ethynylnaphthalene (C12H8), from the reaction of the 2-naphthalenyl radical with C2H2; these results are consistent with the predictions of the kinetic model and the HACA mechanism, but contradict a previous exptl. study that indicated no C14H10 formation in the 2-naphthalenyl + C2H2 reaction. In the 1-naphthalenyl radical + C2H2 reaction system, the primary product measured is C12H8, consistent with the predicted formation of acenaphthylene via HACA. The present work provides direct exptl. evidence that single-radical HACA can be an important mechanism for the formation of PAHs larger than naphthalene, validating a common assumption in combustion models. The experimental part of the paper was very detailed, including the reaction process of 1-Iodonaphthalene(cas: 90-14-2Synthetic Route of C10H7I)

Quality Control of 1-IodonaphthaleneIn 2021 ,《Single-molecule junction formation in break-junction measurements》 was published in Journal of Physical Chemistry Letters. The article was written by Fu, Tianren; Frommer, Kathleen; Nuckolls, Colin; Venkataraman, Latha. The article contains the following contents:

The scanning tunneling microscope-based break-junction (STM-BJ) technique is the most common method used to study the electronic properties of single-mol. junctions. It relies on repeatedly forming and rupturing a Au contact in an environment of the target mols. The probability of junction formation is typically very high (∼70-95%), prompting questions relating to how the nanoscale structure of the Au electrode before the metal point contact ruptures alters junction formation. Here we analyze conductance traces measured with the STM-BJ setup by combining correlation anal. and multiple machine learning tools, including gradient-boosted trees and neural networks. We show that two key features describing the Au-Au contact prior to rupture determine the extent of contact relaxation (snapback) and the probability of junction formation. Importantly, our data strongly indicate that mol. junctions are formed prior to the rupture of the Au-Au contact, explaining the high probability of junction formation observed in room-temperature solution measurements. The results came from multiple reactions, including the reaction of 1-Iodonaphthalene(cas: 90-14-2Quality Control of 1-Iodonaphthalene)

1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Quality Control of 1-Iodonaphthalene

And the article was published in Journal of Coordination Chemistry in 2019. Synthetic Route of C10H7I The author mentioned the following in the article:

A hybrid system involving graphene oxide (GO), magnetic oxide (Fe3O4), acrylamide and dicyandiamide was prepared via amine functionalization of GO/Fe3O4 by covalent bonding with acrylamide and subsequent reaction with dicyandiamide to provide a multinitrogen containing polymer on the surface of GO. This hybrid system was used as a heterogeneous catalyst support for immobilizing Pd nanoparticles to provide the hybrid, Pd@GO/Fe3O4/PAA/DCA. This nano-Pd composite was characterized using FTIR, TEM, SEM, vibrating sample magnetometer, TGA, x-ray diffraction, and ICP techniques and used for promoting Sonogashira cross-coupling under mild reaction conditions. This heterogeneous and magnetic catalyst was easily separated by external magnet and was reused in a model reaction, efficiently up to six times with slight loss of catalytic activity and Pd leaching, showing the suitability of GO/Fe3O4/PAA/DCA for embedding Pd nanoparticles. To check the effect of the number of surface nitrogens of the polymeric chain on the catalytic performance, the activity of the catalyst was compared with Pd@GO/Fe3O4/PAA; increased number of the surface nitrogens on the chain polymer leads to higher loading of Pd and lower the Pd leaching.

We have developed a new one-pot synthesis of α-aryl- and α-heteroaryl-α-trifluoromethyl alcs. carrying not only arenes with electron-withdrawing groups but also electron-deficient nitrogen-containing heteroarenes, which are of increasing interest because these compounds are some of the most important units in current fluorine-containing inhibitors or antagonists. This new method includes three tandem reactions in a one-pot synthesis: (1) the in situ generation of functionalized aromatic and electron-deficient heteroaromatic Grignard reagents, (2) trifluoroacetylation of the generated Grignard reagents with diphenylmethyl trifluoroacetate, and (3) successive Meerwein-Ponndorf-Verley type reduction It offers several advantages, including no need for expensive transition metals and gaseous trifluoromethylating reagents, toleration of not only reducible functional groups on the aryl groups but also electron-deficient nitrogen-containing heterocycles, easy scalability, and the ability to suppress the formation of the bis-aldol product as a byproduct by changing the ester moiety of the trifluoroacetate from an iso-Pr to a diphenylmethyl group.
