2,2-Diethoxyethanol → 1,1'-Oxybis(2,2-diethoxyethane)

참여 물질

반응 단계

Glycolaldehyde diethyl acetal (45.4 g, 338 mmol) was added dropwise to a stirred solution of sodium hydride (14.3 g, 60% dispersion in mineral oil, 357 mmol) in xylene (100 ml), and the reaction heated under reflux for 1 hour. The reaction mixture was cooled to room temperature and bromoacetaldehyde diethyl acetal (100 g, 507 mmol) was added. The resulting solution was heated under reflux for 20 hours, then cooled to room temperature. The solvent was removed under reduced pressure, and the residual solution was distilled under reduced pressure (80° C. @ 6 mm Hg), to afford the title compound as a colourless oil, 60.8 g.
