Homolytic cleavage of molecular oxygen by manganese porphyrins supported on Ag(111).

Oxygen binding and cleavage are important for both molecular recognition and catalysis. Mn-based porphyrins in particular are used as catalysts for the epoxidation of alkenes, and in this study the homolytic cleavage of O2 by a surface-supported monolayer of Mn porphyrins on Ag(111) is demonstrated by scanning tunneling microscopy, X-ray absorption, and X-ray photoemission. As deposited, {5,10,...

Influence of Nitrogen Bases on Epoxidation of Cyclooctene with Sodium Periodate Catalysed by Manganese(III) Porphyrins

Effects of imidazoles and substituted pyridines and pure s-donors on the oxidation of cyclooctene with NaIO4 by 5,10,15,20-tetraphenylporphyrinato-manganese(III) acetate, Mn(TPP)OAc, and 5,10,15,20-Tetramesitylporphyrinato-manganese(III) acetate, Mn(TMP)OAc, catalysts in CH2Cl2-H2O solvent are studied. Coordination of the nitrogen donors to the Mn...

On the mechanism of action of cytochrome P-450. Evaluation of homolytic and heterolytic mechanisms of oxygen-oxygen bond cleavage during substrate hydroxylation by peroxides.

Cytochrome P-450 functions as a peroxygenase in catalyzing the reaction RH + XOOH ROH + XOH where RH represents a variety of hydroxylatable substrates and XOOH a variety of peroxy compounds which serve as oxygen donors, and neither molecular oxygen nor an external electron donor is required. We have previously shown that in the reaction of the phenobarbital-inducible isozyme of rabbit liver mic...

Quantitative Analysis of Molecular Oxygen Using Palladium Porphyrins

A simple optical method for the quantitative determination of dissolved oxygen under physiological conditions is described. The technique involves measurement of room temperature phosphorescence from palladiumfll) porphyrins. Such emission is rare for large organic molecules, and its long lifetime, together with the favourable absorption characteristics of the porphyrin receptor, ensure that th...
