摘要：

We have developed a novel method for the direct C-H functionalization of benzothiazole and benzoxazole using triarylbismuth reagents. The arylation proceeds using the homogeneous catalytic system PdCl2, Cu(OAc)(2) and PPh3 ligand. Triarylbismuthines, which act as threefold arylating reagents, have low toxicity, are green and ecofriendly. These methodologies are particularly useful to prepare arylated benzothiazoles and benzoxazoles. (C) 2016 Elsevier B.V. All rights reserved.
