Title:
Hydrogenation of the ester group by the ruthenium complex of 4 seat amino / imino - Thio ether base, or a carbonyl group
Document Type and Number:
Japanese Patent JP6080774
Kind Code:
B2
Abstract:
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 for the reduction of ketones and/or aldehydes into the corresponding alcohol respectively. Said catalysts are ruthenium complexes comprising a tetradentate ligand (L4) coordinating the ruthenium with: -two nitrogen atoms, each in the form of a primary or secondary amine (i.e. a NH2 or NH group) or N-alkyl imine functional groups (i.e. a C=N group), and -two sulfur atoms, each in the form of thioether functional groups.
