Description	The reaction of 5-amino-3-thioxo-3H-1,2-dithiole-4-carboxylic acid functional derivatives (nitrile, amide, ethyl ester) 1 with alkylation and acylation agents were studied. Ionic 1,2-dithiole-3-ylidene amides 6 were formed in several pathways. Treatment with phosphorus pentasulfide afforded the corresponding 3,3aë4,4-trithia-1-azapentalenes 8. The results from structure study on synthesized heterocycles were described. The combination of X-ray structure analysis, IR spectroscopy, HF and DFT quantum-chemical calculation were involved.
