Title:
PROCESS FOR PREPARATION OF FLUORINE-CONTAINING ALKYL HALIDES
Document Type and Number:
WIPO Patent Application WO/2004/005225
Kind Code:
A1
Abstract:
A process for the preparation of fluorine-containing alkyl halides represented by the general formula (II): Rf-CH2CH2X (II) [wherein X is halogeno; and Rf is perfluoroalkyl having 1 to 20 carbon atoms or polyfluoroalkyl having 1 to 20 carbon atoms], characterized by reacting a fluorine-containing alkene represented by the general formula (I): Rf-CH=CH2 (I) [wherein Rf is as defined above] with a group of reagents capable of generating hydrogen halide in the presence or absence of a catalyst. According to the invention, fluorine-containing alkyl halides can be efficiently prepared from fluorine-containing alkenes, and fluorine-containing esters can be also efficiently prepared by utilizing the process.
