Perfluorinated cyclic hemiketals, corresponding perfluorodiketones and process for preparing them |
| 摘要 |
Perfluorinated cyclic hemiketals of formula: <IMAGE> where n=1-6, m=2-3, and their corresponding perfluoridiketones. The latter are prepared by means of perfluoroalkylation reaction of diacyl fluorides with perfluoroalkyl-trialkyl silanes. The perfluorodiketones can be then reacted with H2O in order to obtain said cyclic hemiketals.
