摘要:
The nitration of 2,3',4'-tricyanobiphenyl with subsequent transformations of the obtained product provided 4-X-2,3',4'-tricyanobiphenyls (X = NO(2), NH(2), NHCOCH(3), Br, I). The condensation of the initial biphenyl or its 4-X-derivatives (X = NO(2), NHCOCH(3), Br, I) in the presence of zinc acetate afforded the corresponding zinc complexes of tetra(4-X-2-cyanophenyl)phthalocyanines.
