A Bimetallic Porphyrin Metal Organic Framework as Multifunctional Catalysts for CO₂ Cycloaddition and Alkyne Hydration

Abstract

Here, a post synthetic modification strategy is presented to prepare multifunctional BiÀ MOFÀ Co by introducing Co atom into the porphyrin units of bismuth-porphyrin metal organic framework (BiÀ MOF). Under milder conditions (0.1 MPa, 80 °C), CO 2 cycloaddition is achieved to form cyclic carbonate in 96 % yield catalyzed by BiÀ MOFÀ Co. The recyclability of catalysts is confirmed by five cycle experiments without loss of activity. Moreover, alkyne hydration is also catalyzed by BiÀ MOFÀ Co in 99 % yield. The hydration protocol exhibites excellent functional group compatibility.
