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.
本发明涉及一种含有磷杂双环碳氢基团的有机膦配体,其中磷杂双环碳氢基团的磷原子进一步被含有至少一个磷氧[P=O]基团或硫氧[S=O]基团的杂碳氢基团所取代。本发明还涉及一种催化剂组合物,用于乙烯基不饱和化合物的氢甲酰化反应,包括一种含有第VIII族金属阳离子的来源和所述有机膦配体。此外,本发明还涉及一种乙烯基不饱和化合物的氢甲酰化反应的方法,包括在所述催化剂组合物的存在下,将该化合物与一氧化碳和氢气接触。
