| 摘要 |
The invention concerns a method for preparing tris[(1H,1H, 2H,2H-perfluoroalkyl) aryl]phosphites. Said method consists in preparing a grignard reagent from an alkoxyhalogenobenzene, then in reacting it with a iodo-1H,1H,2H, 2H-perfluoroalkane; in transforming the alkoxy function of (1H,1H, 2H,2H-perfluoroalkyl) alkoxybenzene obtained into a hydroxy function, then in reacting (1H,1H, 2H,2H-perfluoroalkyl) hydroxybenzene with PCl3. The invention also concerns said fluorinated arylphosphites and their use as transition metal ligand for making catalysts to be used in two-phase catalysis with fluorinated phase. |
