摘要
An efficient and copper-free catalyst system for Sonogashira cross-coupling reaction is presented. In the presence of 3 mol-% of Pd(OAC)(2) and 6 mol-% of 2-aminopyrimidine-4,6-diol, various aryl iodides and bromides can be coupled smoothly with terminal alkynes to afford the corresponding coupled alkynes in moderate to excellent yields under mild conditions.
