Catalytic oxidation of furan and hydrofuran compounds. 3. Synthesis of 2,5-diethoxy-2,5-dihydrofuran in the furan - hydrogen peroxide - aqueous ethanol - vanadyl sulfate system
Abstract
2,5-Diethoxy-2,5-dihydrofuran was synthesized for the first time by the oxidation of furan with hydrogen peroxide in an aqueous ethanol medium in the presence of vanadyl sulfate. The reaction product was characterized by PMR,13C NMR, and IR spectroscopy and chromato-mass spectrometry. It was found that diethyxydihydrofuran is formed as a mixture of cis and trans isomers in a ratio of 2.5∶1. The corresponding dihydrazone of malealdehyde was obtained from the isolated product and 2,4-dinitrophenylhydrazine.
