Organomediator enabled electrochemically regioselective 1,2-arylalkylation of alkenes with aryl and alkyl halides

Alkene difunctionalization represents an efficient methodology for rapidly accessing complex molecular frameworks. Here, we developed a novel electrochemically intermolecular three-component regioselective 1,2-arylalkylation of alkenes with aryl and alkyl halides assisted by dimethyl terephthalate. This method features mild conditions, a wide substrate scope, and no requirement for noble-metal catalysts, and can be applied to the synthesis of 1,1-diarylalkanes. The protocol offers a pioneering strategy for achieving regioselective 1,2-arylalkylation of alkenes <i>via</i> radical pathways.
