Title (EN) PROCESS FOR CATALYTIC HYDRODEFLUORODIMERIZATION OF FLUOROÖLEFINS
(FR) PROCÉDÉ D'HYDRODÉFLUORODIMÉRISATION CATALYTIQUE DE FLUORO-OLÉFINES
Abstract:
(EN) The present application provides a hydrodefluorodimerization process, which is useful in the synthesis of, for example, hydrofluoölefins of Formula (II) that can be used as refrigerants, blowers and the like. The process is an "early-stage fluorination" process, wherein olefinic precursors containing fluorine are assembled into the desired product using a zerovalent nickel catalyst and a hydride source. Also provided are fluoro-bridged dinickel derivatives of Formula (III) and, additionally, liquid compositions comprising one or more fluoroölefins produced by the catalytic process. (Formulae (II), (III))
(FR) La présente invention concerne un procédé d'hydrodéfluorodimérisation, qui est utile dans la synthèse, par exemple, d'hydrofluoro-oléfines de formule (II) qui peuvent être utilisés en tant que réfrigérants, ventilateurs et analogues. Le procédé est un procédé de " fluoration en phase précoce ", dans lequel des précurseurs oléfiniques contenant du fluor sont assemblés dans le produit souhaité à l'aide d'un catalyseur de nickel à valence zéro et d'une source d'hydrure. L'invention concerne également des dérivés de dinickel à pont fluoré de formule (III) et, en outre, des compositions liquides comprenant une ou plusieurs fluoro-oléfines produites par le procédé catalytique. (Formules (II), (III))
