[Formylation reaction in series of meso-tetraaryl substituted porphyrins and chlorins].

The formylation of nickel complexes of meso-tetraaryl substituted porphyrins and chlorins was studied. An obvious regioselectivity was observed for the introduction of the first and subsequent formyl groups into chlorins.
