Chemical Properties

colorless to light yellow liqui

Purification Methods

Partially dry dihydropyran with Na2CO3, then fractionally distil it. The fraction b 84-85o is refluxed with Na until hydrogen no longer evolves when fresh Na is added. It is then dried, and distilled again through a 60 x 1.2cm column packed with glass rings [Brandon et al. J Am Chem Soc 72 2120 1950, UV: Elington et al. J Chem Soc 2873 1952, NMR: Bushweller & O'Neil Tetrahedron Lett 4713 1969]. It has been characterised as the 3,5-dinitrobenzoyloxy-tetrahydrofuran derivative, m 103o which forms pale yellow crystals from dihydropyran/Et2O [Woods & Kramer J Am Chem Soc 69 2246 1947]. [Beilstein 17/1 V 181.]
