描述了一种基于新型联芳基膦配体 (3) 的催化剂,用于 Pd 催化的酰胺和芳基氯的交叉偶联反应。该系统显示了迄今为止报道的这些反应的最高周转频率,特别是对于带有邻位取代基的芳基氯底物。一系列酰胺和芳基氯成功反应,产率良好至优异。
A catalyst based on a new biarylphosphine ligand (3) for the Pd-catalyzed cross-coupling reactions of amides and aryl chlorides is described. This system shows the highest turnover frequencies reported to date for these reactions, especially for aryl chloride substrates bearing an ortho substituent. An array of amides and aryl chlorides were successfully reacted in good to excellent yields.
