TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The metal of organometallic reagent is tin, zinc, silicon, copper, aluminum or gallium. The palladium-trifluorovinyl complex is manufactured using organozinc reagent or lithium salt as catalyst.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organofluoride compound is of formula (III), (IV), (V) or (VI), and is obtained by reacting tetrafluoroethylene and nucleophilic reagent in presence of organic palladium complex or organic nickel complex. The nucleophilic reagent is organometallic reagent. The organic palladium complex is zerovalent palladium complex, zerovalent palladium complex produced using base with bivalent palladium complex, or a complex obtained by mixing compound chosen from phosphine, diamine and bipyridyl. The zerovalent palladium complex is tris(dibenzylideneacetone)dipalladium, bis(cycloocta-1,5-diene)palladium, (1,2-bisdiphenyl phosphino ethane)palladium, bis(tricyclohexyl phosphine)palladium and/or tetra(triphenyl phosphine)palladium. The organic nickel complex is zerovalent nickel complex or zerovalent nickel complex generated using base with bivalent nickel complex, and has a ligand whose cone angle is 170-190 degrees . The organic nickel complex is obtained by mixing zerovalent nickel complex, or the zerovalent nickel complex generated using base with bivalent nickel complex, and compound chosen from phosphine, diamine and bipyridyl. The zerovalent nickel complex is bis(cycloocta-1,5-diene)nickel, bis(cyclodeca-1,5-diene)nickel, bis(cyclododeca-1,5,9-triene)nickel, bis(4-vinyl cyclohexane)nickel, tetra(carbonyl)nickel, bis(tricyclo phosphine)nickel, tetra(phenylphosphine)nickel and/or bis(tricyclohexylphosphine)nickel amine compound ((PCy3)2NiN-CC-NNi(PCy3)2, where Cy is cyclohexyl). The phosphine in organic nickel complex and organic palladium complex is triaryl phosphine or trialkyl phosphine. The fluorine atom in fluoroolefin is substituted by reacting fluoroolefin, nucleophilic reagent and metal halogenated reagent in presence of organic palladium complex or organic nickel complex.R,R'=alkyl or aryl (both optionally substituted). EXAMPLE - A thin red solution obtained by dissolving bis(cycloocta-1,5-diene)nickel in toluene (10 ml) was added into an airtight container, subjected to deaeration and pressure-reduction, then tetrafluoroethylene (0.089 mmol) was added and stirred during which color of the solution was changed to red-orange color, to obtain precipitate of orange crystals. Then, orange crystalline solid obtained by removing supernatant liquid of reaction liquid was washed using pentane and concentrated by adding hexane (7 ml), to obtain tetrafluoroethylene-nickel bis tricyclohexyl phosphine complex as orange fine powder (99 mg).
