使用温和的有机还原剂汉斯酯代替传统金属还原剂或负氢试剂, 发展了一种有效的可见光驱动下过渡金属镍催化的烯烃还原Heck反应. 在无需外源光氧化还原催化剂的条件下, 成功实现了芳基卤化物与丙烯酸酯类型底物的还原氢芳基化反应. 该反应条件简单、温和, 官能团兼容性好, 为烯烃还原Heck反应提供了一种互补的催化策略.

An efficient visible-light induced nickel-catalyzed reductive Heck reaction of alkenes by using mild organic reductant Hantzsch ester (HEH) instead of traditional metal reductants or hydride reagents was developed. The reductive hydroarylation of acrylates with aryl halides was successfully achieved without requiring exogenous photoredox catalysts. This reaction is highlighted by the simple and mild conditions, good functional group tolerance, thus providing a complementary approach for alkenes reductive Heck reaction.

Key words: nickel, reductive Heck reaction, visible light, organic reductant, alkene
