Versuchsvorschrift

1-bromo-3-butene (39.0 mmol) and triethyl phosphite (1 g, 6 mmol) were dissolved and reacted in CHCl3 (30 mL). Then, the reaction solution was refluxed for 12 hours, cooled to room temperature and filtered through a glass filter. Chloroform (CHCl3) was completely removed from the solution under vacuum to thereby give an oily compound as the title compound. The 1H NMR results of the compound thus obtained are given as follows.
