Photo-oxidation of Alcohols by Hexachlorometalate(IV) Ions (M = Pt, Pd, or Ir): Spin Trapping and Matrix Isolation Electron Spin Resonance Studies

Article abstract of DOI:10.1039/DT9890001237

Spin-trapping studies reveal that whereas the mild (λ > 380 nm) photolysis of ions ^2- (M = Pd, Pt, or Ir) in alcohol (RCH2OH)-water mixtures leads invariably to R<*>HOH, in pure alcoholic media many of the oxidations lead to RCH2<*>.Prolonged, wide-band photolysis leads to the production of H atoms.At 77 K, wide-band photolysis leads to the production of platinum(III) and palladium(III) centres, identifies by their g_<*> features, in addition to the expected C-centred organic radicals.
