Photoirradiated and γ-ray-irradiated reactions of manganese(III, IV, V) tetraphenylporphyrins in 2-methyltetrahydrofuran. Reactions of azidomanganese(III) porphyrin

Manganese(III, IV) tetraphenylporphyrins MnIII(TPP)X (TPP = 5,10,15,20-tetraphenylporphinato; X = I, Br, Cl, N3, NCS, OAc) and MnIV(TPP)(OCH3)2 in 2-methyltetrahydrofuran (MeTHF) at room temperature were reduced to yield MnII(TPP) by photoirradiation with visible light (440-750 nm) or by γ-ray irradiation. The photoirradiation of MnIII(TPP)N3 in the rigid matrix at 77 K affords MnV(TPP)N. Photochemically stable MnV(TPP)N was reduced to MnII(TPP) by γ-irradiation at room temperature. γ-Irradiation of MeTHF solutions of MnIII(TPP)X at 77 K causes one-electron reduction to form the constrained complexes [MnII(TPP)X]-. Warming the matrices after γ-irradiation formed MnII(TPP), liberating ligand X-. The near-infrared bands of MnIII(TPP)X red shift along with the shifts of the bands in the visible region by varying the ligand X. The characteristic bands of the constrained complex [MnII(TPP)X]- in the near-infrared region red shift in the order X = Cl > Br > I. The photoirradiation of CrIII(TPP)N3 with visible light affords CrV(TPP)N at room temperature and at 77 K.

The Autoxidation of a Chromium(II) Porphyrin: Synthesis and Structural Characterisation by X-Ray Crystallography of αβγδ-Tetraphenylporphinato-oxochromium(IV)

The reaction of dioxygen with αβγδ-tetraphenylporphinatochromium(II) in toluene proceeds in two stages; a μ-oxo-chromium(III) intermediate is formed initially and this then further reacts with dioxygen to give the title complex, the structure of which has been determined by X-ray crystallography.
