Catalytic efficiency of a novel complex of oxoperoxo molybdenum(VI): Synthesis, X-ray structure and alkane oxidation

A new mononuclear oxo–peroxo complex of molybdenum(VI) of the formula [MoO(O2)(phox)2] (where phox = 2-(2′-hydroxyphenyl)oxazoline) has been synthesized and characterized by X-ray structure analysis, elemental analysis, infrared, UV–visible and 1H, 13C NMR spectroscopy. A monoclinic space group P−1 was determined by X-ray crystallography from single-crystal data of this complex. Complex functions as facile alkane oxidation catalyst with hydrogen peroxide as terminal oxidant at room temperature. The catalyst shows very much efficient reactivity in the oxidation reactions giving high yield, turnover number (TON) and selectivity.

Graphical abstractA new oxo–peroxo molybdenum(VI) complex [MoO(O2)(phox)2] was synthesized and characterized. The complex efficiently catalyzes the selective oxidation of alkanes to the corresponding aldehydes/ketones and alcohols with excellent selectivity using H2O2 as an oxidant.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► A oxo–peroxo molybdenum(VI) complex is applied in oxidation of alkanes. ► Hydrogen peroxide (H2O2) as oxidant. ► Excellent yield, high TONs and selectivity have been achieved.
