Abstract
The present invention relates to a process for the preparation of fluorinated compounds, to novel compounds containing fluorinated end groups, to the use thereof and to compositions comprising novel compounds containing fluorinated end groups.
Claims21
Process for the preparation of compounds of the formula (I)
- comprising firstly preparing compounds of the formula (II)
- and
- these are then converted into compounds of the formula (I),
- where
- Rf is a fluorinated, linear or branched alkyl group, optionally containing further heteroatoms,
- R is a linear or branched alkyl or siloxane group, optionally containing heteroatoms, or a group Rf′, and
- Rf′ is a fluorinated, linear or branched alkyl group, optionally containing further heteroatoms.

Compounds of the formula (II)
- where
- Rf is a fluorinated, linear or branched alkyl group, optionally containing further
- heteroatoms,
- or
- compounds of the formula (I′)
- where
- Rf is a fluorinated, linear or branched alkyl group, optionally containing further heteroatoms,
- R is a linear or branched alkyl or siloxane group, optionally containing heteroatoms, or a group Rf′,
- Rf′ is a fluorinated, linear or branched alkyl group, optionally containing further heteroatoms,
- and, if R is a group Rf′, Rf and Rf′ are different,
- or
- compounds of the formula (VI′)
- where
- Rf is a fluorinated, linear or branched alkyl group, optionally containing further heteroatoms,
- R is a linear or branched alkyl or siloxane group, optionally containing heteroatoms, or a group Rf′,
- Rf′ is a fluorinated, linear or branched alkyl group, optionally containing further heteroatoms,
- L is a single bond or a divalent organic group and
- X is a cationic, non-ionic, amphoteric or anionic group
- and, if R is a group Rf′, Rf and Rf′ are different.
