Abstract

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. ...
