Cyanothioformarnides were reacted with isocyanates, isothiocyanates, aldehydes, acetylenedicarboxylic acid and anthranilic acids to produce imidazolidines, oxazolidines pyrroline, quinazolinones and benzothiazoloquinazolinones, respectively. Interaction of imidazolidineimino(thiones and dithiones) with o-phenylenediamines gave rise to imidazoquinoxalines and imidazoquinoxalinethiones, respectively.
