Molybdatophosphoric Acid/NaNO_2/Wet SiO_2 as an Efficient System for the Aromatization of 1,2-Dihydroquinolines under Mild and Heterogeneous Conditions

摘要

A combination of molybdatophosphoric acid and NaNO2 in the presence of wet SiO2 was used as an effective oxidizing agent for the oxidation of 1,2-dihydroquinolines to their corresponding quinoline derivatives in dichlomethane at room temperature with excellent yields.
