Novel osmium(IV) and -(V) porphyrins. Synthesis, spectroscopy, and electrochemistry

Reduction of [OsVI(P)(O)2] (P = porphyrin dianion) with PPh3, ascorbic acid, or N2H4·H2O in the presence of ROH and RSH yielded [OsIV(P)(OR)2] and [OsIV(P)(SR)2], respectively. [OsIV(OEP)Br2] (H2OEP = octaethylporphyrin) was prepared from [OsVI(OEP)(O)2] and Br2. The dialkoxyosmium(IV) and dibromoosmium(IV) porphyrin complexes are paramagnetic with measured μeff values of 2.27-2.79 μB. which are close to the spin-only values for two unpaired electrons and independent of temperature from -30 to 30°C. The [OsIV(P)(SR)2] species are diamagnetic, suggesting that the RS- ligand is a poor π-donor. The 1H NMR spectral data for the paramagnetic [OsIV(P)(OR)2] and [OsIV(P)Br2] complexes are discussed. For the [OsIV(p-X-TPP)(OEt)2] system [H2(p-X-TPP) = para-substituted tetraphenylporphyrin], the relative isotopic shifts of the phenyl protons are mainly due to dipolar interactions. A large ring current effect on the methine C-H and pyrrolic methylene protons of [OsIV(OEP)X2] has been found. Except for [OsIV(P)(SR)2], the osmium(IV) porphyrins exhibit reversible Os(IV/III) and Os(V/IV) couples. For [OsIV(P)X2], the redox potentials of Os(IV/III) couples decrease in the order of X = Br > PhO > PhS > MeO, EtO > i-PrO. [OsIV(OEP)(OEt)2] can be oxidized to [OsV(OEP)(OEt)2]+ at a potential of 0.13 V vs Cp2Fe+/0. For the [OsIV(p-X-TPP)(OEt)2] system, the redox potentials of Os(V/IV) couples, which lie between 0.27 and 0.37 V, show a linear free energy relationship with the 4σ constants of the para substituents on the four phenyl rings. Oxidation of [OsIV(OEP)(OEt)2] and [OsIV(TPP)(OEt)2] gave the respective [OsV(OEP)(OEt)2]+ and [OsV(TPP)(OEt)2]+, characterized by UV-vis spectroscopy.

Synthesis, reactivity, and X-ray structural characterization of trans-dioxoosmium(VI) porphyrin complexes

The oxidation of [Os(P)(CO)(EtOH)] (P = porphyrin dianion) to [Os(P)(O)2] by m-chloroperoxybenzoic acid in CH2Cl2 proceeds through a stable Os(IV) intermediate. The [Os(p-X-TPP)(O)2] (X = Cl, H, OMe, Me) and [Os

Redox Reactions of Osmium Porphyrins

The metal centre in osmium porphyrinates (OsP) can exist in a wide range of oxidation states, each being stabilised by axial complexation with a particular ligand.Thus OsIIP is stabilised by ligation with a CO molecule.Oxidation occurs readily to form the corresponding OsIIIP which retains the CO ligand and can be reduced quantitatively to the originalOsII complex.Further oxidation gives OsIVP which is stabilised by axial ligation of two alcohol or water molecules.These OsIV complexes are stable to both oxidation and reduction.Treating the OsIIP with an organic peroxide results in formation of an OsVIP complex which is stabilised by two oxo ligands but can be reduced to the OsIVP species.Photolysis of OsIIP and OsIIIP causes loss of the CO ligand, the naked porphyrin species so formed undergoes oxidative reactions with the solvent, O2, or trace impurities, in most cases forming an OsIVP complex.The VIP(O)2> species does not oxidise alkanes or alkenes in the dark at room temperature but does oxidise cyclohexene under visible light irradiation.
