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
