diesters of phosphorous acid were prepared in good yields by the reaction of primary or secondary alcohols, such as methanol, ethanol, and s-butanol, or of phenols, such as phenol, p-chlo-rophenol and p-cresol, with ethyl N-phenylimino phosphite and p-toluenesulfonic acid monohy-drate. Similarly, when carboxylic acids, such as acetic acid, benzoic acid, p-chlorobenzoic acid and trichloroacetic acid, were
通过伯醇或仲醇(如甲醇、乙醇和仲丁醇)或酚(如苯酚、对氯苯酚和对甲酚)与乙基反应制备亚磷酸二酯,收率良好。 N-苯基亚氨基亚磷酸酯和对甲苯磺酸一水合物。同理,上述实验中用乙酸、苯甲酸、对氯苯甲酸、三氯乙酸等羧酸代替一水酸时,也得到亚磷酸二酯。在上述实验中,N-n-丙基亚氨基乙基或N-异丙基亚氨基乙基可以成功地代替N-苯基亚氨基亚磷酸乙酯。此外,甲基次膦酸的各种衍生物,如乙基二氰基甲基-、乙基氰基碳乙氧基甲基-和乙基二碳基乙氧基甲基次膦酸,
