Despite the rapidly growing interest in MOFs, the possibility of combining more than one catalytic site in MOFs to perform tandem reactions remains largely unexplored. 9 The existing few examples involve extensive post-synthetic modification (PSM) of MOFs to incorporate additional functional groups, along with the aid of external additional reagents if necessary. Herein, we demonstrate a tandem reaction, heterogeneously catalyzed by a site-isolated bifunctional MOF, NH 2 - ...
