A method for preparing tris[(1H,1H,2H,2H-perfluoroalkyl)aryl]phosphites consists in preparing a grignard reagent from an alkoxyhalogenobenzene, then reacting it with a iodo-1H,1H,2H,2H-perfluoroalkane; transforming the alkoxy function of (1H,1H,2H,2H,2H-perfluoroalkyl)alkoxybenzene obtained into a hydroxy function, then reacting (1H,1H,2H,2H-perfluoroalkyl)hydroxybenzene with PCl3. The invention also concerns fluorinated arylphosphites and their use as transition metal ligand for making catalysts to be used in two-phase catalysis with fluorinated phase.
制备三[(1H,1H,2H,2H-全氟烷基)芳基]磷酸酯的方法包括从烷氧卤代苯制备格氏试剂,然后将其与碘-1H,1H,2H,2H-全氟烷烃反应;将得到的(1H,1H,2H,2H,2H-全氟烷基)烷氧基苯的烷氧基转化为羟基,然后将(1H,1H,2H,2H-全氟烷基)羟基苯与PCl3反应。该发明还涉及氟化芳基磷酸酯及其用作过渡金属配体,用于制备用于与氟化相一起使用的催化剂的两相催化。
