Heterogenization of molecular organo-iodine oxidation catalysts through incorporation in metal-organic frameworks (MOFS): Tackling the problems of decomposition and deactivation through site-isolation

Abstract

The main goal of this research is to investigate metal-organic frameworks (MOFs) as solid supports for molecular organo-iodine catalysts. To achieve this goal a few different strategies are examined. Firstly, using a multivariate strategy, iodine-functionalized Zr and Al-based metal-organic frameworks (MOFs) are prepared. These MOFs were found to be active heterogeneous catalysts for the oxidation of phenol derivatives. Secondly, a combination of a multivariate and isoreticular approach was employed to ensure an ideal balance between the internal surface area and catalytic site in the pores of the frameworks. The impact of increased pore size and the catalytic activity of the MOFs on the oxidation of more challenging phenol derivatives is discussed. The catalytic oxidation using hypervalent iodine supported metal-organic frameworks is further extended to flow chemistry in consideration of the concepts of green chemistry. Lastly, iodine-containing molecules with the ability to switch their electronic properties in response to an external stimulus are explored. These systems potentially can be used for catalysis purposes in the near future.
