Several new azo compounds were obtained by coupling 2,3’,4’-tricyanodiphenyl-4-diazonium bisulfate with β-naphthol, 3-hydroxy-2-naphthoic and salicylic acids, aniline, 2-toluidine, 2,6-xylidine, and N,N-dibutylaniline. New zinc complexes of tetra-4-[2-cyano-4-(2-hydroxy-1-naphthyldiazenyl)phenyl]phthalocyanine and tetra-4-[2-cyano-4-(4-dibutylaminophenyldiazenyl)phenyl]-phthalocyanine were obtained in 84 % and 67 % yields by condensation of the corresponding azo compounds in the presence of zinc acetate under microwave assistance. This method was also succesfully applied for the preparation of known zinc complexes based on 4-substituted 2,3’,4’-tricyanodiphenyls with enhanced yields.
