corresponding aldehydes) have been herein employed for the successful release of tertiary, α-oxy, and α-amido radicals under photo-organo redox catalysis. The reaction relies on the unprecedented C–C cleavage occurring from the radical cation of these heterocyclic derivatives. Such a protocol is applied to the visible-light-driven conjugate radical addition onto Michael acceptors and vinyl (hetero)arenes
迫切需要开发在温和的光催化条件下被激活的不带电自由基前体。2-取代-
1,3-恶唑烷(E ox < 1.3 V vs SCE,由相应的醛顺利制备)已被用于在光有机氧化还原下成功释放叔、α-氧基和 α-酰胺自由基催化。该反应依赖于这些杂环衍生物的自由基阳离子发生的前所未有的 C-C 裂解。这种协议适用于在温和的无金属条件下将可见光驱动的共轭自由基加成到迈克尔受体和乙烯基(杂)
