Cerium-Hydride Secondary Building Units in a Porous Metal–Organic Framework for Catalytic Hydroboration and Hydrophosphination
摘要:
We report the stepwise, quantitative transformation of Ce-6(IV)(mu(3)-O)(4)(mu(3)-OH)(4)(OH)(6)(OH2)(6) nodes in a new Ce-BTC (BTC = trimesic acid) metal-organic framework (MOF) into the first Ce-6(III)(mu(3)-O)(4)(mu(3)-OLi)(4)(H)(6)(THF)(6)Li-6 metal-hydride nodes that effectively catalyze hydroboration and hydrophosphination reactions. CeH-BTC displays low steric hindrance and electron density compared to homogeneous organolanthanide catalysts, which likely accounts for the unique 1,4-regioselectivity for the hydroboration of pyridine derivatives. MOF nodes can thus be directly transformed into novel single-site solid catalysts without homogeneous counterparts for sustainable chemical synthesis.
