  • Title: A Bifunctional MOF Catalyst Containing Metal-Phosphine and Lewis Acidic Active Sites.
    Author: Prasad RRR, Dawson DM, Cox PA, Ashbrook SE, Wright PA, Clarke ML.
    Journal: Chemistry; 2018 Oct 12; 24(57):15309-15318. PubMed ID: 29979815.
    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.
