《Controllable Synthesis of NiS/rGO Hybrid Composite: An Excellent Counter Electrode for Dye Sensitized Solar Cell》 was written by Indhumathy, M.; Prakasam, A.. Product Details of 516-12-1 And the article was included in Journal of Cluster Science in 2020. The article conveys some information:

We have synthesized an efficient NiS anchored reduced graphene oxide (rGO) nanosheet composites were by a facile hydrothermal route and served as the efficient counter electrodes (CE) for dye-sensitized solar cells (DSSCs). XRD and FESEM results suggest that the electrodes were well crystalline with formation of individual spherical like with homogeneous nanoparticles sizes in the range of 40-30 nm, which is distributed throughout the rGO sheet. The UV-Vis DRS suggest that the absorption edge of all the electrodes were in the visible light region, further it was shifted in the longer wavelength side with the increase of rGO content. The separation, transfer and recombination behavior of the photogenerated charge carriers were analyzed by PL spectra. The NiS/rGO CE produces a power conversion efficiency of 9.25%, which is higher than that (5.21%) for the DSSC with the bare CE. The enhanced efficiency of NiS/rGO hybrid composite is due to reduction of the triiodide caused by the synergistic effects between the extremely catalytic NiS nanoparticles and high elec. conductive nature of rGO sheet. In the experiment, the researchers used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Product Details of 516-12-1)

The recent progress of our research on quaternized poly(arylene perfluoroalkylene)s (QPAFs) as anion exchange membranes (AEMs) for alk. fuel cell applications is reviewed. First, the effect of the perfluoroalkylene group in the polymer main chains on the AEM properties is discussed. We emphasize that the polymer main chains of QPAFs remain intact in harsh alk. environments, and QPAFs have desirable AEM properties, such as well-developed phase-separated morphol., good anion transport, mech. robustness, and gas barrier properties. We then discuss the effect of the mol. structures of the quaternary ammonium groups on the alk. stability of the QPAF membranes. A number of pendant ammonium head groups are much more alk.-stable than the classical benzyltrimethylammonium groups. A comparison of our QPAFs with other state-of-the-art AEMs implies that well-designed aromatic AEMs are potentially applicable for alk. fuel cells that use hydrogen or hydrazine as a fuel.

The author of the article were Yin, Sanmao; Wang, Xiaomin; Jiang, Jun; Xiao, Hongping; Li, Xinhua. The article conveys some information:

Herein, authors prepared two terpyridine-containing Pd(II) complexes, [PdClL1]•solvent (A1) and [PdClL2]•2H2O (A2) (L1 = 4′-(4-carboxyl-phenyl)-2,2′:6′,2”-terpyridine, L2 = 2,6-bis(2-pyrazinyl)-4-(4-carboxyl-phenyl)pyridine), from 4′-(4-cyanophenyl)-2,2′:6′,2”-terpyridine (L1a)/2,6-bis(2-pyrazinyl)-4-(4-cyanophenyl)pyridine (L2a) and Pd(II) acetate and characterize them by several instrumental techniques. A1 and A2 are good catalysts for the coupling of 2-iodobiphenyl with iodobenzenes to afford triphenylenes, which is known to involve dual C-H bond activation and double C-C bond formation. The obtained data suggest that the mechanism of A1-and A2-mediated coupling may be similar to the reference Pd catalysts, A1 and A2 are also suitable catalysts for this cyclization process. Study on this kind of complexes is of importance to the development of novel Pd-based catalysts and triphenylene synthesis techniques.

In 2022,Kato, Daiki; Murase, Tomoya; Talode, Jalindar; Nagae, Haruki; Tsurugi, Hayato; Seki, Masahiko; Mashima, Kazushi published an article in Chemistry – A European Journal. The title of the article was 《Diarylcuprates for Selective Syntheses of Multifunctionalized Ketones from Thioesters under Mild Conditions》.Quality Control of 4-Iodobenzoic acid The author mentioned the following in the article:

Ketones were selectively synthesized from thioesters by using diarylcuprates(I) generated in situ from copper(I) salts and aryl Grignard reagents in a 1 : 1.3-1.5 ratio under ambient temperature During the ketone synthesis, various functional groups, such as carbonyl (ketones, esters, and amides), O-protecting groups, halogens, and heteroarenes, were tolerated to afford multifunctionalized ketones in excellent yields. This copper-mediated ketone synthesis could be applied to the synthesis of not only gluconolactone-derived ketone, a synthetic intermediate in the transformation to the SGLT2 inhibitor canagliflozin, but also thiolactol, a valuable synthetic intermediate for (+)-biotin. Control experiments on an isolated diphenylcuprate(I), [CuPh2]-, and DFT calculations revealed that this ketone synthesis proceeded by oxidative addition of the C-S bond of thioesters to [CuPh2]-, while reductive elimination from the CuIII intermediate produced the corresponding ketone and an inactive species [(RS)CuPh]-, the latter reacted with [CuPh]4 to regenerate the reactive diphenylcuprate(I).
