N2 - An acylation of 5-amino-3-thioxo-3H-1,2-dithiole-4-carboxylic acid functional derivatives led to the formation of N-acyl compound via S-acyl intermediate. On the other hand, alkylation occurred only at the sulfur atom of thioxo group. Structure elucidation of both types of products was done by IR, 1H, 13C NMR and X-ray structural analysis.
