A practical method for preparing α-ketoaryl thioamide by air oxidation has been developed. Under air atmosphere, in the presence of K2CO3 as base and dimethyl sulfoxide (DMSO) as solvent at 120 ℃, a variety of α-ketoarylthioamides were obtained from aryl thioamide in yields of 42%~85%. This reaction has good substrate applicability, metal-free and atomic economy, and provides an efficient, economical, green and convenient method for the synthesis of α-ketoaryl thioamide.

Key words: air, dimethyl sulfoxide (DMSO), K2CO3, green oxidation, α-ketoaryl thioamide
