Reactions of 3-Aroylimino-3H-1,2-dithiolesThe thiolates 3 and 10 prepared from 3-aroylimino-4-aroylthio-5-cyano-3H-1,2-dithioles 1 with bases, react with alkylhalides and acylhalides to the corresponding 4-S-substituted compounds 6, 11 and 7, respectively. Treatment of the thiolates with 1-chloropropanone gives the bicyclic compound 12 by intramolecular cyclization involving the 5-cyano-group. 3,6-Bis-(acylimino)-3H,6H-[4,3-c] [1,2]-dithioles 2 or 8 are prepared from the S-acylated dithioles 1 or 7 and sulphur in pyridine/benzene. 1,2,4-Triazines 13 are formed by the reaction of dithiol es 1 orthiolates 3 with phenylhydrazine. The thiolates give upon protonation the mesoionic dithioliumthiolates 4. Coordination compounds are obtained from the reaction of the thiolates with cations of 3d-elements. On the basis of the chemical behaviour of the new 3-acylimino-1,2-dithioles and the results of spectroscopic measurements a strong bonding interaction between the N-acyl-carbonylgroup and the dithiole ring system in these compounds is supposed.
