Abstract:	Addition of aryl amine and urea derivatives to isothiocyanate 2 yielded thiourea derivatives 3a-c and triazine derivatives 4a,b respectively. Cycloaddition of isothiocyanate 2 and malononitrile, Schiff base and / or enaminone 8 afforded oxazine 15, oxadiazine 7 and / or pyrimidine 9 derivatives respectively.
