reagent, a wide range of alkenes can be converted into acid products via a carboxyl group transfer strategy in an additive-free fashion. Mechanistic studies revealed that radical anion species (CO2•– and carbon radical anions derived from the reduction of alkenes) are key intermediates of the transformation. This method has the advantages of high catalytic efficiency and a simple catalytic system, which
开发了用于羧化的甲酸盐的光氧化还原活化模式。使用甲酸盐作为还原剂、羰基源和氢原子转移试剂,可以通过羧基转移策略以无添加剂的方式将各种烯烃转化为酸性产物。机理研究表明自由基阴离子物质(CO 2 •–和来自烯烃还原的碳自由基阴离子)是转化的关键中间体。该方法具有催化效率高、催化体系简单等优点,有望成为一种有前景的工业应用策略。
