functionalization of cyclopropenes. Starting from cyclopropenyl redox-active esters, easily accessible through the rhodium- or silver-catalyzed cyclopropenation of alkynes, we could access a wide range of diverse cyclopropenes under mild photoredox conditions. The transformation displayed a broad scope and a remarkable functional group tolerance. Mechanistic studies supported aromatic cyclopropenium cations as
我们报告了环丙烯的光催化脱羧功能化。从环丙烯基氧化还原活性酯开始,可以通过铑或银催化的炔烃环丙烯化轻松获得,我们可以在温和的光氧化还原条件下获得各种不同的环丙烯。该转化表现出广泛的范围和显着的官能团耐受性。机理研究支持芳香族环丙烯正离子作为反应中间体。
