Abstract. The Vilsmeier formylation of metallocomplexes of isomeric meta- and para-methoxy-substituted tetraphenylporphyrines has was been studied. Formyl derivatives of meta-isomers were shown to form cyclization products not only in solutions, but also in the the solid state. The ability to undergo such transformations follows decreases in the trend following order: Co > Cu > Ni > Pd > Pt.
Key words: gB-formyl-tetra-meso-(para- and meta-methoxyphenyl)porphyrines, metallocomplexes, intramolecular cyclization
