The Si-C bond of N,N-dimethylcarbamoylsilanes added regiospecifically to the C=C bond of electrophilically functionalized alkenes to afford beta-silyl-beta-functionalized amides. Carbonyl addition products were formed when hindered alkenic esters were used. [reaction: see text]

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.
