- Abstract
We report on the preparation and characterization of two new air‐stable mononuclear molybdenum(VI) complexes, termed MoVIO2(OPNO)2 (<bold>1</bold>) and MoVIO2(SPNO)2 (<bold>2</bold>). The potential of these complexes to act as functional mimics of molybdoenzymes from the DMSO reductase family was investigated. Initial catalytic studies suggest that <bold>2</bold> (but not <bold>1</bold>) catalyzes the reduction of a sulfoxide into the thioether derivative. Studying the catalytic intermediates by UV/Vis spectroscopy, NMR spectroscopy, and DFT indicates that the active species (SPNO)2OMoV–O–MoVO(SPNO)2 (<bold>4</bold>), a dinuclear molybdenum(V) dimer with one µ‐oxo bridge, is formed upon successive reduction of the (SPNO)– ligands and the molybdenum(VI) ion.
