Condensations of accessible imidoalkylating reagents containing a characteristic CCl=NCHCl moiety with thiourea in the absence of bases and in the presence of triethylamine proceed by different routes.In the absence of bases, 6-mercapto-1,2-dihydro-1,3,5-triazine derivatives are mainly formed, whereas in the presence of triethylamine the major reaction products are derivatives of 6-amino-2H-1,3,5-thiadiazine.The structure of these compounds is confirmed by a set of spectral data and also by reactions with 1,2,2,2-tetrachloroethyl isocyanate and p-toluoyl chloride.
