摘要

Abstract: We present (homepage: www. ufsm. br) herein the application of copper nanoparticles/diorganyl dichalcogenides to promote the synthesis of 2-(organochalcogen) thiazoles via direct carbon-hydrogen bond activation in thiazoles. A systematic study of the catalytic system revealed that the presence and amount of base played an essential role in this reaction. The results revealed that electron-donating and electron-withdrawing ...
