    摘要: A two-step process for the preparation of fluoroolefin compounds of formula I wherein R is hydrogen or alkyl, and R1 is alkyl or cyclopropyl, or R and R1 are taken together with the carbon atom to which they are attached to form a cyclopropyl group; Ar is phenyl or naphthyl both of which are optionally substituted; Ar1 is phenoxyphenyl, biphenyl, phenyl, benzylphenyl, or benzoylphenyl, all of which may be optionally substituted, comprising reacting fluorobromoolefin compounds of formula II with organozinc compounds of formula III or IV BrZnCH2Ar1  III Zn[CH2Ar1]2  IV in the presence of a palladium catalyst and a solvent, which compounds of formula II are obtained by reacting aldehyde compounds of formula V with (a) fluorotribromomethane, (b) a tri(substituted)phosphine or a hexaalkylphosphoramide or a mixture thereof, and (c) zinc, in the presence of a solvent, compounds of formula II.

    摘要: Disclosed herein are polymers made by free radically polymerizing the novel compound vinyl(perfluorocyclopropane), and optionally other monomers to form copolymers. The repeat unit formed by vinyl(perfluorocyclopropane) contains an olefinic bond, making it particularly useful as a grafting and/or crosslinking site.
