Page/Page column 7-8, (2010/11/03)
A method for preparing a fluorinated vinyl ether compound comprising reacting a fluorinated ether substrate having (i) a hydrogen atom on a carbon atom that is alpha to an etheric oxygen and (ii) a fluorine atom on a carbon atom that is beta to the etheric oxygen, with an organolithium base to provide a reaction product comprising a fluorinated vinyl ether compound.

Novel compounds have at least one perfluorocyclobutane ring and at least two functional groups suitable for forming condensation polymers. Preferably the compounds have a structures represented by Formula II: STR1 wherein R and R' independently represent optionally inertly substituted groups; X and X' represent any molecular structures which link R and R' with the perfluorocyclobutane ring; n and n' are the number of G and G' groups, respectively; and G and G' independently represent any reactive functional groups or any groups convertible into reactive functional groups. The compound are preferably prepared by a process of thermally dimerizing trifluorovinyl compound to form a compounds of Formula I wherein G represents G or G' in Formula II; X represents X or X' of Formual II; and n represents n or n' of Formula II, to form a compound having a perfluorocyclobutane group.

, (2008/06/13)
Compounds have a structure represented by Formula I: wherein R represents an unsubstituted or inertly substituted hydrocarbyl group; each X is independently selected from the group consisting of groups having at least one non-carbon atom between R and --CF=CF2 ; and m is an integer of from 1 to about 3. Polymers formed from such compounds are also prepared. The compounds are preferably prepared by a method by a process comprising the steps of: (a) forming a salt having anion corresponding to a compound of Formula II: wherein X, R and m are as defined for Formula I; (b) reacting the salt with a 1,2-dihalo-1,1,2, 2-tetrafluoroethane wherein the halo groups are iodine, bromine, chlorine or mixtures thereof, at least one halo group being bromine or iodine, to form a compound of Formula III: wherein X, R and m are as defined for Formula I and each Z is independently iodine or bromine; (c) eliminating the halogen atoms represented by Z to form the perfluorovinyl compound represented by Formula I.

, (2008/06/13)
By reaction of a perfluoro vinyl ether with a perfluoro carbonic acid fluoride perfluorinated ketones of the formula R1 --O--CF(CF3)--CO--R2 with at least 13 carbon atoms may be obtained. These ketones may be used as inert solvents of high boiling point. The reaction is catalyzed by cesium fluoride and carried out in an aprotic polar solvent.
