The emergence of new catalytic strategies that cleverly adopt concepts and techniques frequently used in areas such as photochemistry electrochemistry has yielded a myriad organic reactions would be challenging to achieve using orthodox methods. Herein, we discuss the strategic use anodically coupled electrolysis, an electrochemical process combines two parallel oxidative events, complementary approach existing methods for redox transformations. Specifically, demonstrate electrolysis regio- chemoselective chlorotrifluoromethylation alkenes.

The first example of visible-light-driven reductive carboarylation styrenes with CO2 and aryl halides in a regioselective manner has been achieved. A broad range iodides bromides were compatible this reaction. Moreover, pyridyl halides, alkyl even chlorides also viable method. These findings may stimulate the exploration novel Meerwein arylation-addition reactions user-friendly as radical sources photocatalytic utilization CO2.

Abstract Reported herein is a novel visible‐light photoredox system with Pd(PPh 3 ) 4 as the sole catalyst for realization of first direct cross‐coupling C(sp )−H bonds in N‐aryl tetrahydroisoquinolines unactivated alkyl bromides. Moreover, intra‐ and intermolecular alkylations heteroarenes were also developed under mild reaction conditions. A variety tertiary, secondary, primary bromides undergo to generate )−C(sp 2 moderate excellent yields. These redox‐neutral reactions feature broad substrate scope (>60 examples), good functional‐group tolerance, facile generation quaternary centers. Mechanistic studies indicate that simple palladium complex acts photocatalyst radicals are involved process.
