- Abstract
Post‐synthetic modification of the hafnium metal–organic framework MOF‐808(Hf) to include triarylphosphine ligands is reported. Sulfonated phenylphosphines are incorporated without oxidation to give a "MOF ligand" that can complex late transition metals such as Ir and Rh to give a bifunctional catalyst containing both metal–phosphine complexes and the Lewis acidic framework hafnium metal sites. The metallated phosphine‐bearing MOFs act as fully heterogeneous bifunctional catalysts for tandem reductive amination and hydroaminomethylation reactions. Post‐synthetic modification of hafnium MOF‐808 with sulfonated arylphosphines and precious metal catalyst pre‐cursors generates highly active and tunable bifunctional catalysts for reductive amination reactions, including alkene hydroaminomethylation.
