ABSTRACT:
A process for preparing an Rh-based catalytic system heterogenized on an organic or mineral support, characterized in that: a) a rhodium derivative with a valency state>0 is reduced in an ether or aromatic solvent and in the presence of a compound chosen from the group consisting of lipophilic tertiary amines, lipophilic tertiary amides and lipophilic quaternary ammonium salts, and b) the mixture thus obtained is adsorbed onto a suitable organic or mineral support. Use of the abovementioned catalytic system to hydrogenate a C═C double bond of an α,β-unsaturated carbonyl compound.
