The cis-dichloro-meso-hexaethylporphodimethene-zirconium(IV) complex has been. functionalized to the corresponding dialkyl derivatives [R = Me, PhCH2, Ph], 3-5, displaying a variety of migratory pathways. In the case of benzyl derivative 4, the spontaneous migration, of the first benzyl to the Ligand, 6, is followed by the second one, photochemically induced, thus forming a Zr-porphyrinogen complex, 7. The methyl derivative undergoes thermally induced methane elimination with the metalation. of the meso ethyl chains, 8. Migration of both methyl groups has been, observed in the reaction of 3 with (BuNC)-N-t, with the preliminary formation of eta(2)-imine, rearranging to the corresponding enamine, 9.
