HYDROGENATION OF ESTER, KETONE OR ALDEHYDE GROUPS WITH RUTHENIUM COMPLEXES HAVING A DI-AMINE AND A PHOSPHOROUS-NITROGEN BIDENTATE LIGAND |
摘要 |
<p>The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of specific ruthenium catalysts, or pre-catalysts, in hydrogenation processes with molecular H2 for the reduction of ketones, aldehydes and esters or lactones into the corresponding alcohol or diol respectively. Said catalysts are ruthenium complexes comprising a ligand of the type (N-N) type, in which at least one of said amino groups is a secondary or primary amine (i.e. a NH or NH2) and a ligand of the type (P-N) in which N belongs to a tertiary amino group, a N, N, N' trisubstituted carboxiamide (a C(=N)N moiety) or a N-substituted imidoate (a C(=N)O moiety).</p> |
