AbstractA ligand-free copper-catalyzed C–P cross-coupling reaction of arylmethyl quaternary ammonium salts and diarylphosphine oxides in air is developed. Arylmethyl quaternary ammonium salts with various functional groups and a variety of dialkyl- and diarylphosphine oxides afford C–P cross-coupling products with good yields. This protocol requires no inert atmosphere, no ligand, and simple operation
摘要开发了无配体的铜催化空气中芳基甲基季铵盐和二芳基膦氧化物的C-P交叉偶联反应。具有各种官能团的芳基甲基季铵盐以及各种二烷基和二芳基膦氧化物可提供具有良好收率的C-P交叉偶联产物。该方案不需要惰性气氛,没有配体和简单的操作步骤。 图形摘要
