Synthesis, Structure and Catalytic Properties of Dinuclear MoVI Complexes with Ditopic Diaminotetraphenols

MoVI complexes with novel ditopic diaminotetraphenol ligands have been prepared by using a one‐pot procedure in methanol or DMSO with [MoO2(acac)2] (acac = acetylacetonate) as the molybdenum source. The complexes were characterised with X‐ray diffraction, NMR spectroscopic studies, elemental analysis and IR spectroscopy. In the solid state, the compounds represent either a rodlike molecular or oxido‐bridged polymeric structure. The catalytic activity of the complexes was investigated by oxidising benzyl alcohol and 1‐phenylethanol with hydrogen peroxide to the corresponding aldehyde and ketone, respectively. Furthermore, the catalytic activity was surveyed also in epoxidation of cyclooctene.
