Abstract
A novel MCM-41-supported Mn(III) complex with the nitrogen donor ligand I,1 1-bis(a-pyridyl)-2,6,10-triazaundec-1,10-diene [MCM-41-Mn(NNNN)] shows sign ificantly higher catalytic activity in the oxidation of cyclohexene than it s Schiff base analogue [MCM-41-Mn(NNOO)] at the same surface coverage. Exte nded X-ray adsorption fine structure analysis indicated that at high surfac e coverage isolated anchored Mn complexes are maintained in the former case whereas the latter gives phenoxy-bridged oligomers on the surface of the m esoporous silica support.
