Abstract
The reactivity of 3d-metal solvates [MX2(S)4] and [MX2(S1)m(S2)4−m ] (where S, S1, and S2 are solvent molecules: pyridine, N,N-dimethylformamide, and dimethyl sulfoxide) toward porphyrins with different structures, N-methyloctaethylporphyrin and meso-tetraphenyltetrabenzoporphyrin, is discussed. A strong catalytic effect of solvents and ligands having π orbitals was found and rationalized in terms of trans effect in the coordination sphere of solvate salts. A probable activation mechanism of the trans effect was proposed, and its magnitude was shown to strongly depend on the metal nature.
