Allyl chloride → Butyl ethylpropenylphosphinate

Participants

Reaction Steps

At room temperature, a three-neck flask equipped with stirrer and high-performance condenser is initially charged with 400 g of ethanol and this initial charge is devolatilized by stirring and passing nitrogen through it. Then, under nitrogen, 30 g (0.2 mol) of butyl ethylphosphonite (produced as in Example 3) are added, followed by the dropwise addition of initially 14.5 g (0.25 mol) of sodium ethoxide in ethanol and thereafter 19.1 g (0.25 mol) of allyl chloride. Following a reaction time of 5 hours, the reaction solution is passed for purification through a column charged with Deloxan® THP II and the solvent is removed in vacuo. The product (butyl ethylpropenylphosphinate) is purified by column chromatography to obtain 9.9 g (26% of theory) of butyl ethylpropenylphosphinate as colorless oil.
