Redox-Neutral electrochemical Diazo Coupling: Controlled Synthesis of Olefins and Azines via modulating reaction conditions

Abstract

We report a metal-free, linear paired redox-neutral electrochemical diazo coupling that enables the controllable synthesis of olefins and azines by modulating reaction conditions. The protocol exhibits a broad substrate scope, delivering desired products in good yields and diastereoselectivities. Mechanistic investigations, including control experiments and cyclic voltammetry studies, support a cathodically initiated radical-anion formation pathway.
