The reactivity of Isothiocyanatoazobenzene 2 towards some nucleophiles was investigated. Thus, reaction of isothiocyanate 2 with aromatic amines gave thioureas 3a–d . The reaction of compound 3a with arylidenemalononitriles 4a,b afforded the corresponding 1,3-pyrimidines 7a , b . Thiosemicarbazide 8 and ethyl thiocarbamate 9 were synthesized by interaction of isothiocyanate 2 with hydrazine hydrate
