摘要: The photolytic kinetic properties of a new series intramolecular bridged alkyl cobaloxime complexes Br(O–C3H6-(dmgH))(dmgH))CoIII (2), [H2O(O–C3H6-(dmg))(dmgH2)]CoIII[ClO4 (3), ]Py(O–C3H6-(dmg))(dmgH2)[CoIII]ClO4 (4), [Bzm(O–C3H6-(dmg))(dmgH2)]CoIII[ClO4 (5) and ]Im(O–C3H6-(dmg))(dmgH2)[CoIII]ClO4 (6) their precursor aqua-(3-bromopropyl)cobaloximes (1) were investigated by UV-Vis spectroscopy. products solutions characterized both ESI-MS 1H-NMR techniques. Our results revealed carbon-center radical that is produced from Co–C bond cleavage under photolysis might be linked to the equatorial ligand thus retained in proximity CoII-complex. thermo-gravimetric analysis complex 2 gives same conclusion.
