  • Frontiers Selective Catalytic Oxidation of Benzyl

    2020-3-20 · In this approach HNO 3 initiates the oxidation of alcohols by decomposing NO 2 which further formed HNO 2 with H 2 O. HNO 2 subsequently attacks substrate and generates the products by a series of reactions with releasing NO x. Finally the HNO 3 is regenerated by the NO x oxidation by O 2.
