Zhang, Xiang published the artcileMechanism for Ag (I)-catalyzed decarboxylative chlorination: a DFT study, Quality Control of 1949-41-3, the publication is Theoretical Chemistry Accounts (2016), 135(6), 1-9, database is CAplus.

Ag(I)-catalyzed decarboxylative chlorination of the carboxylic acid with t-BuOCl has been given a systematic theor. study. According to the calculations, the catalytic cycle was assumed to include four steps: proton-coupled two-electron transfer, oxidative decarboxylation, formation of Ag(II)-Cl (chlorine source) and chlorine abstraction. It was first suggested that this kind of reaction is driven by the proton-coupled two-electron transfer, which leads to the formation of Ag(II) species, carboxylate, chloridion and t-BuOH. Then the oxidative decarboxylation and formation of Ag(II)-Cl take place at the same time. The resultant alkyl radical from the former abstracts the chlorine atom of Ag(II)-Cl to give the final product. Based on a comparison of the reactivities among different carboxylic acids, the oxidative decarboxylation was established as the rate-determining step. Moreover, it proceeds preferentially in a concerted dissociative electron transfer pathway.

Copper-catalyzed formation of sulfur-nitrogen bonds can be performed by a dehydrocoupling of aryl thiols with amines. Sulfenamides or sulfonamides can be produced by the use of a copper catalyst in air or under oxygen atm. Furthermore, a reaction involving the combination of a palladium catalyst and a copper catalyst selectively afforded sulfinamides.

Park, Byoungnam published the artcileCarrier channeling and funneling through the C₆₀ self-assembled monolayer/zinc oxide colloidal quantum Dot/MAPbI₃ perovskite functional interfaces, HPLC of Formula: 13822-56-5, the publication is Materials Letters (2022), 131943, database is CAplus.

We demonstrated channeling and funneling of charge carriers through functional interfaces with a configuration of C₆₀ self-assembled monolayer (SAM)/zinc oxide (ZnO) colloidal quantum dots (CQDs)/Ag nanoparticles (NPs)/MAPbI₃. The combination of the localized surface plasmon-resonance (LSPR) effect and the electron accepting capability of the C₆₀ SAM enabled the funneling of carriers under illumination. Photoinduced charge transfer is facilitated by the presence of ZnO CQDs, through which the photoexcited carriers in MAPbI₃ is channeled into the C₆₀ SAM with a large diffusion length. This demonstrates that LSPR-induced charge retention at the interface is potentially applicable to photomemory devices.
