等克分子的二硫代磷酸-O,O-二乙酯与溴代丙二酸二乙酯在氢氧化钠的存在下分别用乙醇和丙酮为溶剂回馏,产生S-双(乙氧甲酰)次甲基-O,O-二烷基二硫代磷酸酯(Ⅷ)(R为C2H5—,i-C6H7—,n-C6H7—,n-C4H9—,ClC2H4—)。初步昆虫试验结果证明R为乙基的化合物对拟谷盗有毒杀作用。

Equimolecular amounts of O,O-diethyl dithio-phosphate and diethyl ester of bromomalonic acid in ethanol or acetone and in the presence of sodium hydroxide react to form compounds of the type.
