Despite widespread use of the deuterium isotope effect, selective labeling chemical molecules remains a major challenge. Herein, facile and general electrochemically driven, organic mediator enabled deuteration styrenes with oxide (D2 O) as economical source was reported. Importantly, this transformation could be suitable for various electron rich mediated by triphenylphosphine (TPP). The reaction proceeded under mild conditions without transition-metal catalysts, affording desired products in good yields excellent D-incorporation (D-inc, up to >99 %). Mechanistic investigations means experiments cyclic voltammetry tests provided sufficient support transformation. Notably, method proved powerful tool late-stage biorelevant compounds.

The merger of electrochemistry and transition metal catalysis has emerged as a powerful tool to join two electrophiles in an enantioselective manner. However, the development electroreductive cross-couplings olefins remains challenge. Inspired by advantages synergistic use with nickel catalysis, we present here Ni-catalyzed cross-coupling acrylates aryl halides alkyl bromides, which affords chiral α-aryl carbonyls good excellent enantioselectivity. Additionally, this catalytic reaction can be applied (hetero)aryl chlorides, is difficult achieve other methods. combination cyclic voltammetry analysis electrode potential studies suggests that NiI species activates oxidative addition bromides single-electron transfer.

Abstract Herein, we report an electroreduction of unactivated alkyl alkenes enabled by [Fe]-H, which is provided through the combination anodic iron salts and silane generated in situ via cathodic reduction, using H 2 O as H-source. The catalytic amounts Si-additive work H-carrier from to generate a highly active species under continuous electrochemical conditions. This approach shows broad substrate scope good functional group compatibility. In addition hydrogenation, use D instead provides desired deuterated products yields with excellent D-incorporation (up >99%). Further late-stage hydrogenation complex molecules drug derivatives demonstrate potential application pharmaceutical industry. Mechanistic studies are performed provide support for proposed mechanistic pathway.
