Diethyl u-thiocyanatophosphonates were prepared by the reaction of diethyl α-hydroxyphosphonates in good to high yields at room temperature by using triphenylphosphine, 2,3-dichloro-5,6-dicyanobenzquinone, and ammonium thiocyanate as a new and a neutral system.
以三苯膦、2,3-二氯-5,6-二氰基苯醌和硫氰酸铵为新的中性体系,通过α-羟基膦酸二乙酯在室温下以良好至高收率反应制备了 u-硫氰酸二乙酯。
