A general iron-catalyzed strategy for the atom-transfer radical cyclization (ATRC) of allylic halide is reported. Critical to this strategy is the use of DPPF [1,1′-bis(diphenylphosphino)ferrocene] as catalyst, which allows for efficient generation of the allylic radical species via a single-electron transfer (SET) process. The feasibility of achieving ATRC reactions of propargyl chlorides is also demonstrated, which affords products with an exocyclic allene moiety.

通过烯丙基自由基进行DPPF催化的原子转移自由基环化

报道了烯丙基卤化物的原子转移自由基环化(ATRC)的一般铁催化策略。该策略的关键是使用DPPF [1,1'-双(二苯基膦基)二茂铁]作为催化剂,该催化剂可通过单电子转移(SET)工艺有效生成烯丙基自由基。还证明了实现炔丙基氯的ATRC反应的可行性,其提供了具有环外烯丙基部分的产物。
