of a nitrile as a mediator to achieve the regioselective intermolecular addition of unstabilized zinc ester enolates (Reformatskyreagents) to 1-alkynes and 1,3-enynes. This reaction is made possible by a reversible addition of enolates to a nitrile (Blaise reaction), generating a zinc aza-enolate that, unlike zinc ester enolates, can add intermolecularly to 1-alkynes and 1,3-enynes.

Reductive defluorination of β-CF3-cinnamates to gem-difluoroalkenes is catalyzed by a nickel hydride intermediate using formic acid. The reaction can produce both fluorine and deuterium in one operation when deuterated formic acid is used.
