Phthalocyanines and related compounds: XLVII. Nucleophilic replacement of chlorine atoms in tetrachlorophthalonitrile. Synthesis of phenyl(alkyl)amino-substituted phthalonitriles and some phthalocyanines based thereon
摘要:
Nucleophilic replacement of chlorine atoms in tetrachlorophthalonitrile by the action of primary and secondary amines was studied. The reactions of tetrachlorophthalonitrile with amines at a ratio of 1: 10 gave with high yields and regioselectivity the corresponding 4,5-diamino-3,6-dichlorophthalonitriles from cyclic secondary amines and 4-amino-3,5,6-trichlorophthalonitriles from primary amines and acyclic secondary amines. 4-Amino-3,5,6-trichlorophthalonitriles were used to synthesize cobalt and zinc phthalocyanine complexes. It was shown that replacement of chlorine atoms in the pyrrolic beta-positions of hexadecachlorophthalocyanines by amino groups is not accompanied by red shift of the long-wave absorption band in the electronic spectra.

Chlorine-containing products of incomplete nucleophilic substitution in tetrachlorophthalonitrile were subjected to further reaction with nucleophiles. The nature of the nucleophiles and the order of their introduction into stepwise nucleophilic substitution in tetrachlorophthalonitrile were shown to be of principal importance for selective synthesis on this basis of phthalonitrile derivatives with various substituents.
