Electrochemical C(sp2)–H/N–H “formal” cross-dehydrogenative coupling of olefins with benzotriazoles for synthesis of N-vinyl benzotriazoles

Abstract

The paper details an electrochemical method that couples olefins with benzotriazoles to form C(sp²)–N bonds, enabling the synthesis of N-vinyl benzotriazoles in moderate to good yields. ⁿBu₄NI functions as both an electrolyte and an iodine mediator, and the method does not require oxidants or metals. It is a highly atom-economical and clean reaction, with hydrogen as the sole byproduct.
