Abstract
Ligand-metal bifunctional ruthenium complexes are efficient catalysts for the liberation of two or more molar equivalents of hydrogen from ammonia-borane, a prospective hydrogen storage medium. In some cases, the mechanism for the dehydrogenation features a ruthenium hydride resting state from which dihydrogen loss is the rate-determining step.
