We report herein the catalytic conversion of allylic esters into the corresponding ketones by the formal deletion of an oxygen atom. The key to the success of the reaction is the dual use of nickel and photoredox catalysts; the former mediates C–O bond activation and C–C bond formation, while the latter is responsible for deoxygenation of the acyloxy group using PPh3 as a stoichiometric reductant.
我们在此报道了通过正式删除氧原子将烯丙酯催化转化为相应的酮。反应成功的关键是镍和光氧化还原催化剂的双重使用;前者介导C-O键活化和C-C键形成,而后者则使用PPh 3作为化学计量还原剂负责酰氧基的脱氧。还完成了用系链烯烃催化取代烯丙酯的氧原子。
