An external oxidant free electrochemical strategy is designed towards the β-scission of strained C–C bonds in cyclopropylamine.

Three‐membered carbocyclic‐ and heterocyclic ring structures are versatile synthetic building blocks in organic synthesis owing to their biological importance. Also, the inherent strain of these three‐membered rings led to their ring‐opening functionalization via C‐C, C‐N, and C‐O bond cleavage. Traditional synthesis and ring‐opening methods of these molecules require the usage of acid catalysts or transition‐metals. Recently, electroorganic synthesis has emerged as a powerful tool for initiating new chemical transformations. In this review, the synthetic and mechanistic aspects of electro‐mediated synthesis and ring‐opening functionalization of three‐membered carbo‐ and heterocycles are highlighted.
