Polysubstituted phthalocyanines by nucleophilic substitution reactions on hexadecafluorophthalocyanines

, p. 338 - 339 (2004)

Nucleophilic substitution reactions on hexadecafluorophthalocyaninato zinc(II) with a variety of O, N, C, and S nucleophiles led to narrowly defined mixtures of polysubstituted phthalocyanines, some of which are completely inaccessible by classical phthalonitrile condensation reactions.
