Many organic compounds contain vinyl groups, so the process has attracted significant interest, especially since the reaction scope includes substituted vinyl groups.
[1] Vinylsiloxane[2] and vinylboranes[3] have also been used as sources of vinyl anion equivalents.These types of reactions require catalysts such as those based on palladium.
The Heck reaction couples an unsaturated halide with an alkene.
[4][5] As originally developed by Walter Reppe, acetylene participates in a variety of metal- or base-catalyzed reaction to afford vinyl derivatives.
The net reaction is vinylation of carbon monoxide.
