The autoxidation of a chromium (II) porphyrin: synthesis and structural characterisation by X-ray crystallography of αβγδ-tetraphenyl-porphinato-oxochromium(IV)
Abstract
The reaction of dioxygen with αβγδ-tetraphenyl-porphinatochromium (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.
