A nickel-catalyzed reductive cross coupling with phosphonium salts and allylic C(sp3)–O bond electrophiles, which granted direct construction of the C(sp2)–C(sp3) bond, is successfully developed. The protocol features broad substrate scope, high-functional-group tolerance, and heterocycle compatibility. Notably, the much more challenging reductive cross coupling with heterocyclic thiazolylphosphonium
镍催化与鏻盐和烯丙基 C(sp 3 )-O 键亲电试剂的还原交叉偶联,可直接构建 C(sp 2 )-C(sp 3 ) 键。该协议具有广泛的底物范围、高官能团耐受性和杂环兼容性。值得注意的是,更具挑战性的与杂环噻唑鏻盐的还原交叉偶联也首次实现。
