A novel homodinuclear manganese(III) complex with N,N '-bis(salicylidene)diethylenetriamine: Synthesis, structure and catalytic activity

摘要

A novel chloride bridged dinuclear manganese(III) complex was prepared and its structure established by X-ray diffraction analysis. The complex showed high selectivity in H2O2 promoted oxidation of cyclohexane and cyclic alkenes. Under optimized conditions, 72% of cyclohexane conversion with 85% of selectivity for alcohol was achieved after 5 h. To the best of our knowledge this activity and remarkable selectivity to cyclohexanol is the highest for a manganese catalyst. (C) 2014 Elsevier B.V. All rights reserved.
