title: Synthesis of symmetric anhydrides using visible light-mediated photoredox catalysis.
abstract: A new approach to anhydride formation is reported via activation of C-O bonds by the Vilsmeier-Haack reagent formed by Ru(bpy)(3)Cl(2) and CBr(4) in DMF. Various aryl and alkyl carboxylic acids are converted to the corresponding anhydrides in excellent yields.
