| Abstract: | Synthesis and Reaction Behaviour of N-(3-Chlorobenzob]thiophene-2-carbonyl)-imino-dithiocarbonic Derivatives 3-Chlorobenzob]thiophene-2-carbonyl-chloride 1 was treated with potassium rhodanide to afford the appropriate acyl isothiocyanate 3 , which adds nucleophilic agents as amines and thioles in good yields. Addition of methanethiole and subsequent alkylation of the dithiocarbamate 7 gives S, S-dimethylimino-dithiocarbonate 8 . 3-Chlorobenzob]thiophene-2-carboxamide 2 reacts with carbon disulphide and phenyl isothiocyanate by chlorine substitution and cyclisation to benzob]thieno2, 3-e]thiazines 9, 10 or 11 . The structure of the final products were determined by analytical and spectroscopical dates. |
