Abstract

<jats:title>Abstract</jats:title> <jats:p>Reactions of oxoethoxomolybdenum(V)porphyrins and substituted phenols were investigated by UV-vis absorption spectra. Ligand substitution or reduction of the metal center proceeded depending on the steric repulsion between the substituents of the phenols and the porphyrin skeletons. Proton transfer from the phenols to the axial ligand of the molybdenumporphyrin initiated the reactions. Parallel outer sphere and inner electron transfer proceeded parallel in the reduction of the molybdenum center.</jats:p>
