Title:
METHOD FOR PRODUCING PERFLUOROALKYL COMPOUND USING MONOHYDROPERFLUOROALKANE AS STARTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/025429
Kind Code:
A1
Abstract:
Provided is a simple method for producing perfluoroalkyl compounds that serve as important intermediates for organic electronic materials, pharmaceuticals, agricultural chemicals, polymer functional materials, etc., the method involving the use of monohydroperfluoroalkanes as a starting material. A base is caused to act on a monohydroperfluoroalkane and a reaction with a carbonyl compound is furthermore carried out, whereby an alcohol having a perfluoroalkyl group is produced. For example, potassium hydroxide is caused to act on trifluoromethane and a reaction with a carbonyl compound is carried out, whereby an alcohol having a trifluoromethyl group is produced.
