σ-adduct complexes of low-valent, late first-row metal complexes are highly unusual, and this is particularly true of d^(10) systems. We have discovered a nickel/phosphine/silyl system that undergoes reaction with H_2 in solution to generate a species best described as Ni^0(η^2-(Si–H))(η^2-H_2) on the basis of multinuclear NMR studies. Theoretical calculations suggest that the Ni center facilitates H atom exchange between the η^2-(Si–H) and η^2-H_2 ligands via interconversion with a higher valent Ni^(II) isomer. This exchange is exploited in the selective, catalytic deuteration of exogenous silanes.
