A metallaphotoredox-catalyzed strategy for the Markovnikov-selective hydroaminocarbonylation of alkynes with amines and 1 atm of CO is reported, offering a novel and complementary platform for accessing α,β-unsaturated amides. This synergistic protocol facilitates an unprecedented sequential hydroaminocarbonylation/radical alkylation process with tertiary and secondary alkyl boronate esters.

通过光氧化还原/镍双催化实现炔烃的发散氨基羰基化

报道了一种金属光氧化还原催化策略，用于炔烃与胺和 1 个大气压的 CO 的马尔科夫尼科夫选择性氢氨基羰基化，为获取 α,β-不饱和酰胺提供了一个新颖的补充平台。这种协同方案促进了前所未有的连续氢氨基羰基化/自由基烷基化过程，其中包含叔和仲烷基硼酸酯。
