Document Type and Number:
WIPO Patent Application WO/2005/003062
Kind Code:
A2
Abstract:
The invention aims at providing a process by which fluorinated sulfonyl fluorides having various molecular structures can be obtained efficiently and inexpensively with production problems solved. The invention provides a process which comprises reacting a compound of the general formula (1F): (FSO2-)nRA(-E-RB)m with fluorine in a liquid phase to obtain a compound of the general formula (2): (FSO2-)nRAF(-EF-RBF)m and decomposing this compound into a compound of the general formula (3): (FSO2-)nRAF(-EF1)m, wherein RA is a (n+m) valent organic group having two or more carbon atoms; RAF is a group derived from RA through fluorination or the like; RB and RBF are each a monovalent fluorinated organic group or the like; E is -COOCH2- or the like; EF is -COOCF2- or the like; EF1 is -COF or the like; n is an integer of 2 or above; and m is an integer of 1 or above.
