Nucleophilic substitution in 4-bromo-5-nitrophthalodinitrile: VIII. Synthesis of 4-(benzotriazol-1-yl)-5-[4-(1-methyl-1-phenylethyl)phenoxy]phthalodinitrile and phthalocyanines on its basis

Nucleophilic aromatic substitution of the bromine atom in 4-bromo-5-nitrophthalodinitrile by a 2-aminophenylamine residue followed by conversion of the resulting compound to 4-(1-benzothiazol-1-yl)-5-nitrophthalodinitrile and nucleophilic substitution of the nitro group by a 4-(1-methyl-1-phenylethyl)-phenoxy group gave 4-(benzotriazol-1-yl)-5-[4-(1-methyl-1-phenylethyl)phenoxy]phthalodinitrile. The latter product was reacted with certain metal acetates and chlorides to obtain the corresponding metal complexes of octasubstituted phthalocyanines. Spectral properties of the complexes were studied.
