LIGAND, CATALYST AND PROCESS FOR HYDROFORMYLATION

摘要

The invention relates to an organophosphine ligand comprising a phosphabicyclohydrocarbyl group in which the phosphorus atom of the phosphabicyclohydrocarbyl group is further substituted with a heterohydrocarbyl moiety containing at least one phosphorus oxide [P=O] group or sulfur oxide [S=O] group. The invention also relates to a catalytic composition for the hydroformylation of an ethylenically unsaturated compound, comprising a source of Group VIII metal cations and said organophosphine ligand. Furthermore, the invention also relates to a process for the hydroformylation of an ethylenically unsaturated compound comprising contacting the latter compound with carbon monoxide and hydrogen in the presence of said catalytic composition.
