Hydrogenation of ketones with a manganese PN3P pincer pre-catalyst
Résumé
A catalytic hydrogenation of carbonyl derivs. with a manganese pre-catalyst has been developed. The key feature is the use of an air stable cationic manganese pre-catalyst bearing a tridendate ligand with a 2,6-(diaminopyridinyl)diphosphine scaffold. Under 50 bar of H2, at 130°, various ketones were reduced to the corresponding alcs. with moderate to good yield.
