Abstract
Transition metal hydride species have been implicated in the mechanism of action of the industrial catalysts used for hydrodesulphurization (HDS) and the natural enzymes nitrogenase and iron- and iron-nickel hydrogenases. Common features of these mechanisms are that the hydride reactions occur at a metal centre coordinated by at least two sulphur ligands, that dihydrogen gas is formed or activated and that various H/D exchange processes involving D2(g) are catalysed by the metal centres. The topic of this paper is another possible common feature — the presence of the η2-dihydrogen ligand; that is H2 coordinated side-on to the metal with the H-H bond intact.
