BACKGROUND OF THE INVENTION Since difluoroalkenes have an active carbon-carbon double bond, they serve as an extremely useful building block when synthesizing a fluorine-containing compound. If a functional group can be further introduced into such difluoroalkenes, various conversion reactions using the functional group can be carried out, and the usefulness as a building block will be further expanded. Further, the obtained fluoroalkene is expected to be a raw material for a monomer of a functional fluoropolymer.

The present inventors have previously made a trialkylborane act on a vinyl anion easily obtained from 2,2,2-trifluoroethyl tosylate to utilize an alkyl group 1,2-rearrangement of a boronate complex. Developed a synthetic method of difluoroalkenes by substitution reaction at the difluorovinyl position, which was considered impossible in the past (Tetrahedron Letters Vol. 3).
