both aliphatic and aromatic aldehydes proceeds with air-stable (hetero)arylboronic acids, with an exceptionally wide substrate scope. The neutral condition tolerates acidic hydrogen and sensitive polar groups and also preserves α-stereocenters of some chiral aldehydes. Interestingly, this nickel(0) catalysis does not follow common 1,2-insertion of arylmetal species to aldehydes and β-hydrogen elimination
脂族和芳族醛的镍催化芳基化反应与空气稳定的(杂)芳基硼酸一起进行,底物范围特别宽。中性条件耐受酸性氢和敏感的极性基团,并且还保留了一些手性醛的α-立体中心。有趣的是,这种镍(0)催化反应并不遵循芳基金属物种对醛和β-氢消除的常见1,2-插入。
