The electron-transfer-induced photocyclization reactions of a series of N- and C-silylmethallyl-substituted iminium and 1-benzyl-1-pyrrolinium salts have been investigated in order to gain information about their mechanistic course and to probe their synthetic potential. The results obtained from these studies demonstrate that diradical cation intermediates formed in these processes can be transformed
已经研究了一系列 N-和 C-甲硅烷基甲代烯丙基取代的亚胺盐和 1-苄基-1-吡咯啉盐的电子转移诱导的光环化反应,以获得有关其机理过程的信息并探讨其合成潜力。从这些研究中获得的结果表明,在这些过程中形成的双自由基阳离子中间体可以通过两种相互竞争的机制途径转化为产物,包括自由基偶联或烯丙基或苄基电离基团的丢失
