Acetyl chloride → 1-Acetyl-2-Diethoxyphosphoryl Hydrazine

反応手順

Diethylphosphorohydrazidate (5.3 g) and triethylamine (13 ml) were dissolved in dichloromethane (15 ml). To this solution was added dropwise with stirring and cooling a solution of acetyl chloride (7.4 g) in dichloromethane (15 ml). The mixture was then stirred at ambient temperature and then filtered to remove the triethylamine hydrochloride after the addition of 50 ml of anhydrous diethylether. The filtrates were stripped on a rotary evaporator to yield a red-brown oil which was distilled under high vacuum to give a pale yellow liquid, b.p. 180° C./1 mm, identified as the product.
