olefination of aliphatic aldehydes with arylboroxines is described. The simple rhodium(I) complex [Rh(cod)OH]2 without any external ligands or additives is able to catalyze the reaction in air and neutral conditions, allowing the construction of aryl olefins in an efficient manner with a good functional group tolerance. The mechanistic investigation illustrates that the binary rhodium catalysis is the key
描述了一种铑催化的脂肪醛与芳基环硼氧烷的烯化反应。无需任何外部配体或添加剂的简单铑 (I) 配合物 [Rh(cod)OH] 2能够在空气和中性条件下催化反应,从而以有效的方式构建具有良好官能团耐受性的芳基烯烃。机理研究表明二元铑催化是转化的关键,它涉及 Rh(I) 催化的 1,2-加成和 Rh(III) 催化的消除。
