Electro-Oxidative C-H Alkylation Of Quinoxalin-2(1h)-Ones With Organoboron Compounds

Radical cleavage of C-B bonds to accomplish C-H functionalization is synthetically appealing but practically challenging. We report herein a mild electro-oxidative method for efficient C-H alkylation of quinoxalin-2(1H)-ones by means of radical addition reactions of alkyl boronic acids and esters and alkyl trifluoroborates to afford C-C coupled products.
