Notes:
Cyclic voltammetry was used to characterize the oxidation-reduction behavior of a series of novel hexacoordinate silicon(IV) porphyrin complexes. Each (Por)SiX2 [Por = the dianions of the porphyrins: tetrakis(p-tolyl)porphyrin (TTP), tetraphenylporphyrin (TPP), tetrakis(p-trifluoromethylphenyl)porphyrin (TTFP), octaethylporphyrin (OEP), × = F, Cl, O3SCF3] complex undergoes one to two oxidations and one to two reductions, all occurring at the porphyrin ring. No silicon(IV) reduction is observed for any of the porphyrin complexes. The effects of solvent, supporting electrolyte, substituents on the porphyrin ring, axial ligands, certral metal, and ruffling of the porphyrin ring are described.
