The one-pot successive reactions of Grignard reagents with carbon disulfide and amines mediated by 1-trifluoromethylsulfonylbenzotriazole or triflic anhydride, provide and attractive and general route to thioamides. A wide variety of amines (primary alkyl, arylalkyl, secondary alkyl, cyclic amines, aniline, N-substituted anilines, heterocyclic amidines, amino alcohols, amino ethers, amino acetals, amino ketones, amino esters, amino amides (peptides), aminoalkenes, and diamines) and Grignard (primary alkyl, arylalkyl, aryl, secondary alkyl and tertiary alkyl) can be used, and thioamides are generally formed in good to moderate yields.
