【Abstract】 Triphenylamine can be readily prepared in excellent yield by copper catalyzed cross-coupling reaction of iodobenzene and diphenylamine.Influences of various bases,organic solvents and reaction time were discussed.According to the experimental results,the optimized reaction conditions were determined as follows:by using NaH as a base and copper as a catalyst,diphenylamine is coupled with iodobenzene to generate triphenylamine in high yield.更多还原
