Wang, Long published the artcileHigh-Lying 3¹Ag Dark-State-Mediated Singlet Fission, Recommanded Product: 1-Iodohexane, the publication is Journal of the American Chemical Society (2021), 143(15), 5691-5697, database is CAplus and MEDLINE.

Singlet fission (SF), the conversion of one high-energy singlet to two low-energy triplets, provides the potential to increase the efficiency of photovoltaic devices. In the SF chromophores with C_2h symmetry, exemplified by polyenes, singlet-to-triplet conversion generally involves a low-lying 2¹A_g dark state, which serves as either a multiexciton (ME) intermediate to promote the SF process or a parasitic trap state to shunt excited-state populations via internal conversion. This controversial behavior calls for a deep understanding of dark-state-related photophysics involving the higher-lying singlet state. However, the optical “dark” and “transient” nature of these dark states and strong correlation feature of double exciton species make their characterization and interpretation challenging from both exptl. and computational perspectives. In the present work combining transient spectroscopy and multireference electronic structure calculations (XDW-CASPT2), we addressed a new photophys. model, i.e., a high-lying 3¹Ag dark-state-mediated ultrafast SF process in the benzodipyrrolidone (BDPP) skeleton. Such a 3¹Ag dark state with distinctive double excitation character, described as the ME state, could be populated from the initial 1¹Bu bright state on an ultrafast time scale given the quasi-degeneracy and intersection of the two electronic states. Furthermore, the suitable optical band gap and triplet energy, high triplet yield, and excellent photostability render BDPP a promising SF candidate for photovoltaic devices. These results not only enrich the arsenal of SF materials but also shed new insights into the understanding of dark-state-related photophysics, which could promote the development of new SF-active materials.

Despite the efficiency comparable to crystalline silicon photovoltaics, it is still a severe concern on the long-term stability under the stress of heat, light, and bias potential for perovskite solar cell (PSC). Here, we report a triple aza[6]helicene-based mol. semiconductor (TBTA[6]H) characteristic of a fully fused conjugated backbone. TBTA[6]H presents superior solubility and glass-transition temperature (T_g). An air-doped composite of TBTA[6]H with a high elec. conductivity of 353μS cm^-1 is still featured by a T_g of 112°C, enabling the fabrication of 22% efficiency, 85°C durable PSCs. The TBTA[6]H composite not only exhibits an excellent morphol. stability at 85°C in PSCs, but also remarkably attenuates the thermal degradation of photoactive perovskite layer. The cell with TBTA[6]H also displays an excellent operation stability under the continuous full sunlight soaking at 55°C.

3-Iodopropionic acid (3-IPA) can be efficiently synthesized from the glycerol derivative glyceric acid (GA), which is a potential biomaterial-based platform mol. In this report, Et 3-iodopropionate was rapidly dimerized to di-Et adipate in a microwave reactor using NiCl₂.6H₂O as a catalyst, co-catalyzed by Mn and the 1, 10-Phenanthroline monohydrate ligand. Under the optimum reaction conditions, di-Et adipate can be obtained with 84% yield at 90°C in just 5 min. Di-Et adipate was hydrolyzed to obtain the adipic acid (AA) in 89% yield with an acid catalyst. AA is an important chem. and a monomer for producing a wide range of high-performance polymeric substances. This rapid coupling method is also applicable to other alkyl halides.

Xie, Li published the artcileDetermination of hypochlorite and bisulfite in water by bifunctional colorimetric sensor based on octupolar conjugated merocyanine dyes, Quality Control of 638-45-9, the publication is Microchemical Journal (2022), 172(Part_A), 106931, database is CAplus.

In this study, we developed a bifunctional colorimetric fluorescent sensor based on three merocyanine structures for the detection of hypochlorite (ClO^–) and bisulfite (HSO₃^–). In MeOH solution and under special conditions, this sensor shows high selectivity on fluorescence and UV-Vis spectra for the detection of ClO^– and HSO₃^–, resp. The sensor solution exhibits a strong red fluorescence emission at 638 nm, which was quenched and the blue color turned to purple pink rapidly upon the addition of ClO^–. The mechanism of the detection of ClO^– was confirmed via ESI-MS that the C=C groups were induced to produce ethylene oxide and ethylene glycol derivatives by hypochlorite. The fluorescence emission at 638 nm in the concentration range of ClO^– from 0 to 24 μM showed a good linear relationship (R² = 0.9919), and the LOD of the sensor for ClO^– was 0.42 μM. Interestingly, the sensor can also detect HSO₃^– in acid condition (pH less than 7.4). The blue shift of UV-Vis spectra of the solution of sensor were observed after addition of HSO₃^– and irradiation with visible light for about 4 min. The HSO₃^– concentration showed a good linear relationship (R² = 0.9987) at 275 nm in the range of 12-42 μM, and thus its LOD was calculated to be 1.14 μM. Finally, the sensor has important value for detecting ClO^– and HSO₃^– in tap water and lake water.

Li, Hong-Liang published the artcilePalladium-Catalyzed Enantioselective C(sp³)-H Arylation of 2-Propyl Azaaryls Enabled by an Amino Acid Ligand, Product Details of C6H13I, the publication is Organic Letters (2022), 24(6), 1286-1291, database is CAplus and MEDLINE.

A palladium(II)-catalyzed enantioselective arylation of unbiased secondary C(sp3)-H bonds was developed. The enantioselectivity was controlled by the combination of a pyridyl or isoquinolinyl directing group and an amino acid, N-Boc-2-pentyl proline. A variety of 2-Pr azaaryls and biaryl iodides were employed to provide arylated products in moderate to good yields (up to 82%) with high enantioselectivities (up to 93:7 er). This reaction is a rare example of an amino-acid-enabled enantioselective acyclic methylene C(sp3)-H arylation. Furthermore, the reaction proceeded with high enantioselectivity even on a gram scale, and the product was transformed to a 5,6,7,8-tetrahydroisoquinoline bioactive mol. Kinetic isotope effect (KIE) experiments indicated that C-H activation is the rate-determining step for the enantioselective C(sp3)-H arylation.

Diverse transformations of 2-alkylthiobenzamides were established to synthesize 2,3-dihydrobenzothiazin-4-ones, benzoisothiazol-3-ones and 2-alkylthiobenzonitriles in the presence of Selectfluor. Both NaI-HI and TFA-Ac₂O systems control the selective C-S bond cleavage and C-H bond functionalization to access 2,3-dihydrobenzothiazin-4-ones and 2-substituted 2,3-dihydrobenzothiazin-4-ones, resp. Notably, this was the first example of using Selectfluor as a methylene source to construct important 2,3-dihydrobenzothiazin-4-ones. In the presence of HCl, benzoisothiazol-3-ones were obtained in good yields. Furthermore, 2-alkylthiobenzonitriles could also be prepared using the same NaI-HI system via a thioether-directed and Selectfluor-mediated dehydration of 2-alkylthiobenzamides.

Deuker, Marius published the artcileTetraorganylargentate(III) Complexes: Key Intermediates in Silver-Mediated Cross-Coupling Reactions, COA of Formula: C6H13I, the publication is Organometallics (2021), 40(14), 2354-2363, database is CAplus.

The use of silver as a catalyst in cross-coupling reactions remains underdeveloped. Authors show by electrospray-ionization mass spectrometry that the diorganylargentates LiAgR’₂·Li(CN) (R’ = Me, Bu) formed in situ react with a wide scope of alkyl and aryl halides RX to afford the tetraorganylargentate(III) complexes R’₃AgR^–. Upon fragmentation in the gas phase, these high-valent species readily undergo reductive elimination. The trimethylorganylargentates Me₃AgR^– furnish the synthetically desired cross-coupling products MeR with high selectivity, whereas the tributylorganylargentates Bu₃AgR^– yield more of the homocoupling product Bu₂. Quantum chem. calculations reproduce the exptl. observed trends in reactivity and moreover provide insight into the structures and energetics of the species involved. Their findings indicate that the facile formation of tetraorganylargentate complexes and their high tendency toward reductive elimination can be exploited for the development of silver-mediated cross-coupling reactions as a viable alternative to established synthetic methods.
