Oxidative decarboxylative arylation reactions are potentially attractive routes to generate biaryl structures from simple and readily available precursors; yet, they are underutilized, because of limitations in the carboxylic acid scope. Here, we report a nickel catalyst system that enables the selective decarboxylative arylation of unactivated C–H bonds with a broad scope of (hetero)aromatic carboxylate
氧化脱羧芳基化反应是从简单易得的前体生成联芳基结构的潜在诱人途径。然而,由于羧酸范围的限制,它们没有得到充分利用。在这里,我们报告了一种镍催化剂体系,该体系能够使未活化的CH键与广泛的(杂)芳族羧酸酯偶联伙伴进行选择性脱羧芳基化。初步的力学见解表明,该协议的效率和选择性源自Ni和Ag之间的合作。
