Abstract
Official abstract text for this publication.
The present invention relates to fluorine compounds (I), (II) and (III), to processes for the preparation thereof, and to the use thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compound of the formula (I), (II) or (III) where Rf is a group of the formula CF 3 —(CF 2 ) a —O b —(CF 2 ) c —O d —, where a=1, 2 or 3, b=0 or 1, c=0, 1, 2 or 3 and d=0 or 1. 2. The compound of claim 1 , wherein Rf is a group of the formula CF 3 —(CF 2 ) 1-3 — or CF 3 —(CF 2 ) 1-3 —O—. 3. A process for the preparation of a compound of the formula (I) of claim 1 which comprises reacting a compound of the formula (IV) with glycidol (V) to give the compound of the formula (I): 4. A process for the preparation of a compound of the formula (II) of claim 1 which comprises reacting a compound of the formula (IV) with a compound of the formula (VI) to give the compound of the formula (II): 5. A process for the preparation of a compound of formula (III) of claim 1 which comprises reacting a compound of the formula (IV) with a compound of the formula (VII) to give the compound of the formula (III): 6. A method for the preparation of a compound of the formula (VIII) where Rs is an optionally fluorinated alkyl group and n is a number of from 5 to 20, which comprises reacting a compound of the formula (I) of claim 1 . 7. A method for the preparation of a compound of the formula (IX) where Rs is an optionally fluorinated alkyl group and n is a number of from 5 to 20, which comprises reacting a compound of the formula (II) of claim 1 . 8. A process for the preparation of a compound of the formula (X) where Rs is an optionally fluorinated alkyl group and n is a number of from 5 to 20, which comprises reacting a compound of the formula (III) of claim 1 .
