Abstract
The present invention relates to the field of catalytic hydrogenation and, more particularly, to the semi-hydrogenation of an allene into the corresponding alkene in the presence of a homogeneous catalytic system wherein the homogeneous catalytic system comprises a cobalt salt, a bidentate diphosphine ligand and a weakly or non-coordinating mono anion or a reducing agent.
Claims15
A process for the semi-hydrogenation, using molecular H2, of an allene into the corresponding alkene wherein said process is carried out in the presence of a a homogeneous catalytic system wherein the homogeneous catalytic system comprises a cobalt salt, a bidentate diphosphine ligand and a weakly or non-coordinating mono anion or a reducing agent.
