Herein, an electrochemical approach toward the ring opening functionalization of methylenecyclopropanes (MCPs) via C–C bond cleavage in the presence of alcohols is reported. The methodology avoids the usage of external oxidants and shows good functional group tolerance. The mechanistic studies suggest that the reaction proceeds via direct single electron oxidation of the C–C bond of MCPs followed by ring opening to form the desired product.

亚甲基环丙烷与醇的电化学氧化C-C键断裂

本文报道了一种在醇存在下通过C-C 键断裂实现亚甲基环丙烷 (MCP) 开环官能化的电化学方法。该方法避免了外部氧化剂的使用，并显示出良好的官能团耐受性。机理研究表明，该反应通过MCP 的 C-C 键的直接单电子氧化进行，然后开环形成所需的产物。
