The Triethylamine Catalyzed Reaction of N,N-Disubstituted Thioamide-Bromine Adducts With Unsubstituted Thiobenzamide

Corsaro, Antonino,Compagnini, Anna,Perrini, Giancarlo,Purrello, Giovanni

, p. 897 - 900 (2007/10/02)

The reaction of N,N-disubstituted thioamide-bromine adducts with unsubstituted thioamide, followed by treatment with triethylamine, affords novel N'-thiobenzoylamidines along with smaller amounts of secondary products.A mechanism is proposed for the formation of the amidines.The results give an insight into the initial steps of the mechanism by which thioamides are converted into 1,2,4-thiadiazoles.
