Ten typical P,N-bidentate ligands were selected to synthesize the corresponding Au(I) complexes. The catalytic system of Au(I) complex/metal salt was employed in the catalytic oxidation of terminal alkynes with the oxidant of 8-methylquinoline N-oxide. And then 2,4-disubstituted thiazoles were synthesized from the oxidized alkynes and thioamides. It was found that the catalytic system of 5 mol% Mor-DalPhosAuCl/10 mol% Zn(NTf2)2 showed the optimum catalytic performance in this reaction via adjusting reaction parameters. Furthermore, ten kinds of 2,4-disubstituted thiazoles were effectively synthesized in one-step. So a simple and direct synthetic route was explored for the preparation of thiazoles and their derivatives.
