EFFICIENT CATALYST FOR THE FORMATION OF POLYARYL HYDROCARBONS SUITABLE AS PRECURSORS FOR POLYDENTATE ORGANOPHOSPHORUS CATALYST LIGANDS

The disclosure relates to the efficient preparation of aromatic hydrocarbons useful as intermediates for di-, tri-, tetra- and poly-dentate organophosphorus ligands having value in particular as hydroformylation catalysts. The use of triarylphosphine halide catalysts have been found to be more efficient in forming these intermediates by the use of excess triarylphosphine in an amount beyond what is required to form a coordination complex. 本公开涉及可用作特别作为加氢甲酰基化催化剂具有价值的二-、三-、四-和多齿有机磷配体的中间体的芳烃的高效制备。已经发现在形成这些中间体时使用三芳基膦卤化物催化剂更有效，其通过使用超过形成配位配合物所需的量的过量三芳基膦。
