Abstract

Oxo-manganese-tetraphenylporphyrin (0=Mn^IV-TPP) has been prepared by an oxygen-transfer reaction from iodosylbenzene to Mn^IITPP and characterized by its i.r. and field desorption mass spectra, which are identical to those of the product obtained by direct oxidation of Mn^III(TPP) in an aqueous medium; it transfers oxygen to triphenylphosphine to produce tri-phenylphosphine oxide, and it is suggested that similar intermediates are important in oxygen activation by cytochrome P-450 as well as in the photosynthetic evolution of oxygen.
