Table 2. Transfer hydrogenation of various carbonyl com-
Ru(0)-CHNAP-MgO. The transfer hydrogenation reaction
was carried under reflux at 858C. 1H NMR, MS and IR anal-
yses confirmed the identity of the products. The reusability
of the catalyst was tested after washing the used catalyst
with 2-propanol followed by drying at 1008C.

atmosphere. The solid was filtered, washed with deionized
water, acetone and dried overnight at 1108C toobtain Ru-
(III)-CHNAP-MgO. The final Ru(0)-CHNAP-MgO catalyst
was obtained after hydrogenation of the solid at 2808C fo r
4 h. The prepared Ru(0)-CHNAP-MgO catalyst was gray in
color and from the elemental analysis, the Ru content was
determined tobe 1.64 mmolg À1(Ru content: 16.6 wt%).

General Procedure for the Transfer Hydrogenation of
Carbonyl Compounds with Ru(0)-CHNAP-MgO
Catalyst
A reaction mixture containing 1 mmol of the substrate,
5 mL o f 2-propanol and KOH in 2-propanol (0.1 mol), was
placed in a two-neck, round-bottomed flask equipped with a
septum port, reflux condenser and a guard tube. To this mix-
ture were added 50 mg of freshly vacuum-dried catalyst
