A convenient method for C-S cross-coupling of aryl bromides with various thiols has been developed that involves the use of a 1,1'-bis(diphenylphosphino)ferrocene (DPPF)-ligated palladium complex with N,N-diisopropylethylamine (DIPEA) as the base. This coupling is tolerant of a wide range of functional groups, including hydroxy, amino, cyano, nitro, formyl, and carboxyl groups.
已开发出一种用于芳基溴化物与各种硫醇的 CS 交叉偶联的便捷方法,该方法涉及使用 1,1'-双(二苯基膦基)二茂铁 (DPPF)-连接的钯配合物与 N,N-二异丙基乙胺 (DIPEA) 作为基地。这种偶联可耐受多种官能团,包括羟基、氨基、氰基、硝基、甲酰基和羧基。
