Abstract:  By condensation of O-alkylhydroxylamines with chlorides of diphenylphosphoric and phenylphosphoric acids and with phosphorus trichloride oxide the corresponding mono-, bis-, and tris(O-alkylhydroxylamides) of these acids have been prepared. Mono-O-alkylhydroxylamides were also synthesized in the reaction of free bases of O-alkylhydroxylamines with diethyl or diphenyl esters of hydridophosphoric acid in the presence of carbon tetrachloride. In acid medium the O-alkylhydroxylamides hydrolyze to form O-alkylhydroxylammonium salts. In base medium the ester groups are saponified, and, moreover, in bis- and tris(O-alkylhydroxylamides) a partial cleavage of P—N bonds takes place.
