Inserting CO2 into Aryl C-H Bonds of Metal-Organic Frameworks: CO2 Utilization for Direct Heterogeneous C-H Activation

Angew Chem Int Ed Engl. 2016 Apr 25;55(18):5472-6. doi: 10.1002/anie.201511484. Epub 2016 Apr 15.


Described for the first time is that carbon dioxide (CO2 ) can be successfully inserted into aryl C-H bonds of the backbone of a metal-organic framework (MOF) to generate free carboxylate groups, which serve as Brønsted acid sites for efficiently catalyzing the methanolysis of epoxides. The work delineates the very first example of utilizing CO2 for heterogeneous C-H activation and carboxylation reactions on MOFs, and opens a new avenue for CO2 chemical transformations under mild reaction conditions.

Keywords: C−H activation; X-ray diffraction; carbon dioxide fixation; heterogeneous catalysis; metal-organic frameworks.
