Low loading supported copper catalysts have been used to selectively reduce saturated and unsaturated carbonyl compounds through hydrogen transfer from 2-propanol. The effect of the catalyst support and of the donor alcohol have been investigated in detail in the reduction of 4-tert-butyl-cyclohexanone allowing to put in light a dehydrogenation-hydrogenation mechanism. The dehydrogenation reaction has been used to selectively transform secondary aliphatic alcohols into ketones in the presence of styrene as hydrogen acceptor.

Abstract
Low loading supported copper catalysts have been used to selectively reduce saturated and unsaturated carbonyl compounds through hydrogen transfer from 2-propanol. The effect of the catalyst support and of the donor alcohol have been investigated in detail in the reduction of 4-tert-butyl-cyclohexanone allowing to put in light a dehydrogenation-hydrogenation mechanism. The dehydrogenation reaction has been used to selectively transform secondary aliphatic alcohols into ketones in the presence of styrene as hydrogen acceptor.
