Abstract
Synthesis and Reaction Behaviour of N-(3-Chlorobenzo[b]thiophene-2-carbonyl)-imino-dithiocarbonic Derivatives 3-Chlorobenzo[b]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-Chlorobenzo[b]thiophene-2-carboxamide 2 reacts with carbon disulphide and phenyl isothiocyanate by chlorine substitution and cyclisation to benzo[b]thieno[2, 3-e]thiazines 9, 10 or 11. The structure of the final products were determined by analytical and spectroscopical dates.
