Rieke zinc has been found to be a very selective reducing agent of alkynes to cis-alkenes, allowing for the reduction of enynes to 1,3-dienes, diynes to enynes or dienes, and of propargylic alcohols to cis-allylic

A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from ene-yne unsaturated compounds. The accelerators are especially useful for facilitating the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene or cyclohexene.
