The development of benzyltriphenylphosphonium salts as alkyl radical precursors using photoredox catalysis is described. Depending on substituents, the benzylic radicals may couple to form C–C bonds or abstract a hydrogen atom to form C–H bonds. A natural product, brittonin A, was also synthesized using this method.
描述了使用光氧化还原催化开发作为烷基自由基前体的苄基三苯基
鏻盐。根据取代基的不同,苄基可以偶联形成 C-C 键或夺取氢原子以形成 C-H 键。使用这种方法还合成了一种
天然产物 Brittonin A。
