Bifunctional Metal-Ligand Catalysis:Hydrogenations and New Reactions within the Metal-(Di)amine Scaffold

摘要

The observation of the ligand-associat-ed heterolytic splitting of H_2 dates back to pioneering work by Fryzuk et al.on organometallic amide complexes of rhodium and iridium.'1' The general importance of the reversible storage of dihy-drogen within a transition metal/ligand framework was later proposed by Crab-tree but remained restricted to the stoichiometric formation of hydrides of iridium-amide complexes.
