| titleOfInvention | Process for the preparation of fluorinated benzene sulfonyl fluorides |
| abstract | The present invention relates to a process for the preparation of a fluorinated benzene sulfonyl fluoride comprising the step of: heating a benzene sulfonyl fluoride of the Formula (I) ##STR1## where Y is fluorine, chlorine, bromine, iodine, a methyl group, an ethyl group, or a propyl group; p is 0 to 3; and q is 2 to 6, in the presence of an alkali metal fluoride under conditions and for a time sufficient to provide a fluorinated benzene sulfonyl fluoride of the Formula (II) ##STR2## where x is 1 to 5; m=q-x; and Y and p are as defined above. The present invention also provides novel benzene sulfonyl fluorides of the Formula (III) ##STR3## where each Y is meta or para to --SO 2 F and is independently selected from the group consisting of chlorine, fluorine, fluorosulfonyl, methyl group, ethyl group, and propyl group; and p is 1 or 2. n The fluorinated benzene sulfonyl fluorides are versatile fluorinated intermediates. They are readily converted to sulfonamides of potential activity, or the sulfonyl group can be converted into another functional group, or removed to provide fluorinated benzenes. |
