An electron donor–acceptor complex-enabled, nickel-catalyzed three-component net-reductive 1,2-alkylacylation of alkenes is developed. This conjunctive reductive acyl cross-coupling process obviates the use of an exogenous photocatalyst and a stoichiometric metal-based reductant, affording various synthetically useful 1,3-dicarbonyl compounds in good yields with a broad substrate scope and excellent
开发了一种电子给体-受体复合物,镍催化的三组分净还原烯烃 1,2-烷基酰化。这种联合的还原酰基交叉偶联过程避免了使用外源光催化剂和化学计量的金属基还原剂,以良好的收率提供各种合成有用的 1,3-二羰基化合物,具有广泛的底物范围和出色的官能团耐受性。烷基和酰基亲电试剂均源自高度丰富且易于获得的羧酸,使催化的 1,2-二碳官能化更具综合性和可持续性。
