Title (EN) EFFICIENT CATALYST FOR THE FORMATION OF POLYARYL HYDROCARBONS SUITABLE AS PRECURSORS FOR POLYDENTATE ORGANOPHOSPHORUS CATALYST LIGANDS
(FR) CATALYSEUR EFFICACE POUR LA FORMATION D'HYDROCARBURES POLYARYLE APPROPRIÉS EN TANT QUE PRÉCURSEURS POUR DES LIGANDS DE CATALYSEURS ORGANOPHOSPHORÉS POLYDENTÉS
Abstract:
(EN) 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.
(FR) L'invention concerne la préparation efficace d'hydrocarbures aromatiques utiles en tant qu'intermédiaires pour des ligands organophosphorés di-, tri-, tétra- et poly-dentés ayant une valeur, en particulier, en tant que catalyseurs d'hydroformylation. L'utilisation de catalyseurs à halogénure de triarylphosphine s'est avérée être plus efficace dans la formation de ces intermédiaires par l'utilisation de triarylphosphine excédentaire dans une quantité au-delà de ce qui est nécessaire pour former un complexe de coordination.
