Abstract

A convenient method for the synthesis of aryl thioamides from aryl aldehydes and tetramethylthiuram disulfide (TMTD) in the presence of CuI and di-tert-butyl peroxide (DTBP) avoids the use of a sulfurating reagent. The protocol offers broad substrate scope, very good yields, operability and uses commercially available and inexpensive raw materials.
