Valuable building block for the introduction of the CF2 group by Reformatsky reaction with aldehydes. A further development of this chemistry involves the generation of an ɑɑ-difluoro-?-lactone, followed by thermal decarboxylation as a high-yield route to 1,1-difluoroalkenes: J. Org. Chem., 60, 5378 (1995).
