The chemical reaction of molecular hydrogen (H2) with another substance, generally an unsaturated organic compound, and usually under the influence of temperature, pressure, and a metal catalyst. There are several types of hydrogenation reactions. They include (1) the addition of hydrogen to reactive molecules; (2) the incorporation of hydrogen accompanied by cleavage of the starting molecules (hydrogenolysis); and (3) reactions in which isomerization, cyclization, and so on, result. Other reactions that involve molecular hydrogen and catalysts are reductive amination (hydroammonolysis) and hydroformylation (oxo reaction). See also: Hydroformylation; Hydrogen; Organic synthesis
