PEG‐N2O4 System as an Efficient Reagent both for the Rapid Oxidation of Urazoles and 1,4‐Dihydropyridines under Nonaqueous Conditions
Journal of the Chinese Chemical Society Vol. 55, No. 3, 704–711
چکیده
Abstract N2O4 was easily impregnated on polyethyleneglycol to give a stable reagent. Polyethyleneglycol‐N2O4 (PEG‐N2O4) system was used as an effective oxidizing agent for the oxidation of urazoles and bis‐urazoles to their corresponding triazolinediones and also for the aromatization of 1,4‐dihydropyridines into the corresponding pyridine derivatives under mild conditions at room temperature with good to excellent yields.
