OXIDATION OF 1,2-DIHYDROQUINOLINES UNDER MILD AND HETEROGENEOUS CONDITIONS

Abstract

A combination of NaHSO₄.H₂O and Na₂Cr₂O₇.2H₂O in the presence of wet SiO₂ were used as an effective oxidizing agent for the oxidation of 1,2-dihydroquinolines to their corresponding quinoline derivatives in dichloromethane at room temperature with excellent yields.
