Oxidations with cis-dioxomolybdenum(VI) tetra p-tolyl porphyrin

Henry Ledon; Michel Bonnet

Abstract Tertiary phosphines are oxidized by cis -dioxomolybdenum(VI) tetra p -tolyl porphyrin. The rate of reaction is mainly dependent of the steric hindrance of the phosphine. Relevance to a possible mechanism of molecular oxygen activation by cytochrome P 450 dependent monooxygenases is discussed.

Electrochemical activation of a metal oxo bond; oxidation of cis-dioxomolybdenum(VI) tetraphenylporphyrin

Tadeusz Malinski; Henry Ledon; Karl M. Kadish

The one electron oxidation and coupled oxygen atom transfer of cis-dioxomolybdenum(VI) tetraphynylporphyrin, O2Mo(TPP), was investigated by the use of cyclic voltammetry and thin-layer spectroelectrochemistry.

Photoejection of a dioxygen ligand during the photolysis of bisperoxomolybdenum(VI) porphyrin. Synthesis and characterisation of cis-dioxo-molybdenum(VI) tetra-p-tolylporphyrin

Henry Ledon; Michel Bonnet; Jean-Yves Lallemand

Photolysis of bisperoxo-molybdenum(VI) porphyrins with a tungsten lamp produces the related cis-dioxomolybdenum(VI) complex.
