Functionalized Zr-based metal-organic frameworks (UiO-66-fun) have emerged as promising class of porous functional materials with very large specific surface area, ultrahigh porosity and chemical tunability as well as high stability in water and humid environments, which results in desirable properties for several catalytic applications.1–3 These high stable materials were selected as supporting molecular MOF catalysts. We have applied a simple and highly efficient method for synthetic post-functionalization of new and readily recoverable molecular catalysts that combines the catalytic active transition-metal complexes with the architecture of nano-size MOF and their application for cross coupling reactions. In the catalytic process, substituted aryl halides and arylboronic acids converted into corresponding biaryls through C-C bond forming process in a milder condition (Chart 1). In the tested catalysis reactions, functionalized nano-size UiO-66-fun catalysts can be recovered by simple filtration/centrifugation in air and reusable without significant loss of catalytic activity and while framework structures are maintained stable. The detailed post-functionalization and catalysis results will be presented. References: Kim, M.; Cahill, J. F.; Fei, H.; Prather, K. A.; Cohen, S. M. J. Am. Chem.
