New Synthetic Routes to lsothioammelides, lsothioammelines and their Thioethers. Part II. Interaction of Carbondisulphide with S-Benzylamidinoisothiocarbamides

University Department .of Chemistry and Laxrninarayan Institute of Technology, Nagpur University, Nagpur Manuscript received 2 April 1973; accepted 24 July 1973 In continuation to the earlier work,1'2 interaction of 1-p-tolyl-3-p-tolylarnidino-S-benzylisothiocarbamide and unsubstituted amidinothiocarbamide with carbon disulphide and appropriate followup treatment have been shown to result in the related cyclic products the thiadiazines, thioammelides, thioanunelines and their thioethers. Structures of all the thioammelides as also of some of the other products have been confirmed by their independent synthesis
