An alternative route to tethered Ru(II) transfer hydrogenation catalysts

A new route towards a series of tethered η6-arene/Ru(II) catalysts for use in the transfer and pressure hydrogenation of ketones and aldehydes to alcohols is reported. The route proceeds through the formation of an amide from the diamine precursor, followed by reduction, rather than the direct alkylation of the diamine. This has the advantage that dialkylation of the amine is avoided during the synthesis. Through this new route, both racemic and enantiomerically-pure η6-arene/Ru(II) tethered catalysts can be prepared in high yield.

COMPLEXES AND METHODS FOR THEIR PREPARATION

The invention provides methods for the preparation of ligands for complexes, methods for preparing complexes and complexes having those ligands. Also provided is the use of a complex as a catalyst in a method of synthesis.

Application of tethered ruthenium catalysts to asymmetric hydrogenation of ketones, and the selective hydrogenation of aldehydes

An improved method for the synthesis of tethered ruthenium(II) complexes of monosulfonylated diamines is described, together with their application to the hydrogenation of ketones and aldehydes. The complexes were applied directly, in their chloride form, to asymmetric ketone hydrogenation, to give products in excess of 99% ee in the best cases, using 30 bar of hydrogen at 60 °C, and to the selective reduction of aldehydes over other functional groups.
