Abstract

Microwave irradiated C–S cross-coupling reaction to synthesize 5-aryllthiobenzo-2,1,3-thiadiazole derivatives from a variety of benzene thiols with 5-bromo-2,1,3-benzothiadiazole, catalyzed by Cu(I) iodide and potassium carbonate as a cost-effective base in DMF, was conducted, affording excellent yields of the desired products. Microwave conditions assisted in the development of C–S cross-coupling reaction with higher yields.

Key words

CuI - 5-bromo-2,1,3-benzothiadiazole - thiophenols - MW irradiation­ - DMF
