摘要

Catalytic synthesis of 2-substituted benzothiazoles from thiobenzanilides was achieved in the presence of a palladium catalyst through C− H functionalization/C− S bond formation. This method features the use of a novel catalytic system consisting of 10 mol% of Pd (II), 50 mol% of Cu (I), and 2 equiv of Bu4NBr that produced variously substituted benzothiazoles in high yields with good functional group tolerance.
