Abstract
The present invention provides a process for synthesizing 3-fluoroalkoxymethyl-3-alkyloxetanes suitable as intermediates for preparing various fluorine-containing functional materials, the process comprising using 3-alkyloxetane methanol as a starting compound and adding the compound to a fluoroolefin in the presence of an alkali.
Claims5
A process for preparing a 3-fluoroalkoxymethyl-3-alkyloxetane represented by General Formula (I) or a mixture thereof, the process comprising adding a 3-alkyloxetane methanol (1) to at least one of fluoroolefins (2) under an alkali condition:
- wherein, X1, X2 and X3 independently represent hydrogen or fluorine;
- Rf represents fluorine or C1-C18 linear or branched perfluoroalkyl;
- and R represents methyl, ethyl, n-propyl or isopropyl.
