Gaseous hydrogenation
Hydrogenation has three components, the unsaturated substrate, the hydrogen (or hydrogen source) and, invariably, a catalyst. The reduction reaction is carried out at different temperatures and pressures depending upon the substrate and the activity of the catalyst. The same catalysts and conditions that are used for hydrogenation reactions …
