METHOD FOR PRODUCING HYDROGEN-CONTAINING FLUOROOLEFIN COMPOUND

An unsaturated hydrogen-containing fluoroolefin compound is obtained by bringing an unsaturated fluorine-containing halogen compound into contact with 0.1 to 3 molar equivalents of hydrogen relative to the unsaturated fluorine-containing halogen compound in a vapor phase in the presence of a supported palladium catalyst in which an amount of supported palladium is 0.1% by weight to 2.5% by weight.

Fluorination of fluoro-cyclobutene with high-valency metal fluoride

Fluorinations of 1,4,4-trifluorocyclobutene and 3,3,4,4- tetrafluorocyclobutene using high-valency metal fluorides such as CoF 3, MnF3, AgF2, CeF4 and KCoF 4, and elemental fluorine were examined. In these reactions with CoF3 and MnF3, vic-difluorination proceeded mainly. While, 1,4,4-trifluorocyclobutene yielded 3,3,4,4-tetrafluorocyclobutene, and 3,3,4,4-tetrafluorocyclobutene yielded 1,3,3,4,4-pentafluorocyclobutene mainly in the case of AgF2. The further fluorinated products were increased under severer conditions. Also, the plausible reaction mechanism was suggested.
