Shifts towards metal catalyzed reactions using rare earth metals such as ruthenium and iridium have opened the door to reactions that were once considered unviable using conventional methods. Despite their wide utility, their high cost inhibits their use on an industrial scale. Abundant earth metal organic frameworks (MOFs) have been gained notice as cheaper alternatives to these costly, non-reusable metal catalysts. Modification of traditional MOFs using 2-amino moieties resulted in formation of titanium based MIL-125-NH<sub>2</sub>and MIL-125-NHCyp as well as iron based MIL-101-NH<sub>2</sub>. These MOFs showed an increase in photocatalytic conversion potential with the capacity to facilitate varying and unique photo redox reactions. Our work focuses on establishing the full scope of these MOFs and their application in organic reactions. This includes the oxygenation of sulfide compounds to sulfone and sulfoxide in ambient conditions without the use of conventional oxidants. As well as the reduction of nitro compounds to oximes. Oximes are valuable precursors to a multitude of pharmaceuticals but their synthesis has relied heavily on toxic metal salts and harsh reaction conditions in the past. Successful photocatalytic reactions using cheap, reusable MOFs will expand the range and production possibilities of reactions that once relied on expensive and low abundant metal catalysts.
