Abstract: Metallabis(dicarbollides), such as COSAN and their chlorinated derivatives or FESAN demonstrated to perform efficiently as photoredox catalysts in the oxidation of alcohols and alkenes in water, through single-electron transfer (SET) processes. This was possible thanks to their high water solubility, surfactant behavior and lack of luminescence upon excitation by light. Furthermore, COSAN has been suported on silica-coated amino funcionalized nanoparticles, through non-covalent interactions, (MSNPs-NH2@H[1]), showing high water stability. The heterogeneous catalytic system was highly efficient for the photooxidation of alcohols and their recyclability was demonstrated through 12 runs, maintaining the activity of the catalyst. We have also synthesized the cooperative photoredox catalyst, [RuII(trpy)(bpy)(H2O)][3,3’-Co(1,2-C2B9H11)2]2, and their efficiency in the oxidation of alcohols was demonstrated, operating through proton-coupled electron transfer (PCET) processes.
