Interaction of 1,4-phenylenediisothiocyanate 1 with aromatic amines and o-phenylenediamine furnished the novel bisthiourea, derivatives 2a-c and 7. Hydrazines or o-aminothiophenol reacted with 1 to produce bis-(thiosemicarbazide 4a,b or benzothiazole 9) derivatives. Bisquinazolines 12a,b and bisthienopyrimidines 13a,b were synthesized through interaction of 1 with anthranilic acids 10a,b and aminothiophenes 11a,b. Interaction of 1 with two moles of either salicylic acid or N-(4-substituted-phenyl)cyanothioformamide yielded the corresponding bis(1,3-benzoxazine 14 or imidazolidineiminothiones 16) derivatives.
