文摘

Heterolytic cleavage of dihydrogen into a proton and a hydride ion is a fundamentally important step in many reactions, including the oxidation of hydrogen by hydrogenase enzymes and ionic hydrogenation of organic compounds. We report the facile, reversible heterolytic cleavage of Hb>2b> in a manganese complex bearing a pendant amine, leading to the formation of a manganese hydride and a protonated amine that undergo H⁺/H^{鈥?/sup> exchange at an estimated rate of >107 s鈥? at 25 掳C.}
