摘要：

A simple and ligand-free protocol has been developed for the Pd(OAc)(2)-catalyzed Suzuki reaction of potassium aryltrifluoroborates in aqueous ethanol under air. In the presence of Pd(OAc)(2) and 1 equiv. of K2CO3, aryl or heteroaryl halides coupled with various potassium aryltrifluoroborates smoothly to afford the products in high yields with the highest turnover frequency (TOF) up to 4656 h(-1), and a series of triphenylamine derivatives were prepared efficiently in this system. In addition, the active catalyst was proved to be the in situ-generated palladium nanoparticles according to TEM analysis and mercury-poisoning test.
