The first methodology for the direct reductive deoxygenation of ketones catalyzed by high‐valent oxo‐rhenium complexes by using a silane as reducing agent is described. The systems PhSiH 3 /[ReOCl 3 (SMe 2 )(OPPh 3 )] (2 mmol/5 mol %) and PhSiH 3 /[ReOCl 3 (PPh 3 ) 2 ] (2 mmol/5 mol %) proved to be efficient for the deoxygenation of aryl ketones, producing selectively the corresponding alkane, or a mixture of alkane and alkene derivatives with the alkane as the major product.
