Triethyl phosphite → 2-((Diethoxyphosphoryl)methoxy)ethyl acetate

Participants

Reaction Steps

A mixture of 1-acetoxy-2-(chloromethoxy)ethane (67.8 g, 444 mmol) and triethylphosphite (81.3 g, 490 mmol) was heated at 105°-110° C. for 12 hours. Vigorous gas evolution was noted initially. The reaction mixture was next cooled to room temperature and the crude material purified by distillation (0.9 mmHg, 130°-134° C.) to afford 76.9 g (68%) of 1-acetoxy-2-(diethylphosphonomethoxy)ethane as a colorless liquid.
