Abstract Glycerol, an increasingly abundant by‐product of biodiesel production, is selectively converted to ketomalonic acid in one pot at pH 10 using NaOCl as regenerating oxidant in water at 2 °C in the presence of catalytic Br − along with the radical TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl). The reaction can also be conducted at completion over a sol‐gel silica glass doped with the nitroxyl radical. Considering the stability and versatility of such doped glasses, these materials show real promise as reusable metal‐free catalysts for the conversion of a readily available and renewable biofeedstock into a highly valued compound.
