Tunable Catalytic Activity of Solid Solution Metal–Organic Frameworks in One-Pot Multicomponent Reactions

The
aim of this research is to establish how metal–organic frameworks
(MOFs) composed of more than one metal in equivalent crystallographic
sites (solid solution MOFs) exhibit catalytic activity, which is tunable
by virtue of the metal ions ratio. New MOFs with general formula [InxGa1–x(O2C2H4)0.5(hfipbb)] were prepared
by the combination of Ga and In. They are isostructural with their
monometal counterparts, synthesized with Al, Ga, and In. Differences
in their behavior as heterogeneous catalysts in the three-component,
one pot Strecker reaction illustrate the potential of solid solution
MOFs to provide the ability to address the various stages involved
in the reaction mechanism.
