Selective hydrogenation of aldehyde with complexes of Ru based bidentados

摘要

Abstract selective hydrogenation of aldehyde with complexes of Ru based bidentados.The present invention relates to processes for the reduction by hydrogenation, using H2 molecular, a substrate of C5 - C20, containing one or two functional group (s) (is) aldehyde (s) in alcohol or diol corresponding, characterized by the fact that this process is carried out in the presence of P. At least one catalyst or pre catalyst.In the form of a complex of ruthenium with a coordination sphere of the n2p2o2, in which the atoms coordenantes N2 are supplied by a first binder bidentado, atoms coordenantes P2 are supplied by a second binder bidentado, and atoms coordenantes O2 are supplied by two L Nonlinear igantes of carboxylate; and optionally an additive acid.
