Abstract

The nitration of 2,3′,4′-tricyanobiphenyl with subsequent transformations of the obtained product provided 4-X-2,3′,4′-tricyanobiphenyls (X = NO2, NH2, NHCOCH3, Br, I). The condensation of the initial biphenyl or its 4-X-derivatives (X = NO2, NHCOCH3, Br, I) in the presence of zinc acetate afforded the corresponding zinc complexes of tetra(4-X-2-cyanophenyl)phthalocyanines.
