Base-free Hiyama coupling reaction via a group 10 metal fluoride intermediate generated by C-F bond activation

A Pd(0)-catalyzed Hiyama coupling reaction of tetrafluoroethylene (TFE) proceeded without the use of a base to give α,β,β- trifluorostyrene derivatives. A Ni(0)-catalyzed Hiyama coupling reaction of perfluoroarenes also occurred without a base. The key intermediate in these reactions would be a transition-metal fluoride complex that is generated in situ by the oxidative addition of a C-F bond.

METHOD FOR PRODUCING SUBSTITUTED FLUORINE-CONTAINING OLEFIN

This invention relates to a method of reacting fluoroolefin with an organic magnesium compound in the presence of a catalyst comprising nickel or palladium so as to efficiently produce fluoroolefin, such as TFE, in which a fluorine (F) atom or atoms bonded to the sp2 hybridized carbon atom are substituted with an organic group.

Room temperature preparation of trifluoroethenylzinc reagent by metalation of the readily available halocarbon HFC-134a and an efficient, economically viable synthesis of 1,2,2-trifluorostyrenes

Trifluoroethenylzinc reagent [CF2=CFZnX] was generated from the readily available halocarbon HFC-134a by an in situ metalation-transmetalation procedure at temperatures near to room temperature (15-20 °C). By systematic standardization of the m
