Abstract

An ionic complex has been obtained from N2O4 in the presence of the macrocyclic ether 18-crown-6. This crystalline compound was used as an effective oxidizing agent for the oxidation of dihydropyridines to their corresponding pyridine derivatives at room temperature with excellent yields.
