Abstract
p-Dialkylaminoarylphosphinous acids are prepared by action of phosphorus trichloride upon an excess of the dialkylarylamines; a diluting agent such as benzene may be present; the phosphenyl chlorides so produced are then hydrolyzed to the corresponding acids or salts, for instance by means of caustic soda. Substitution products of the dialkylarylamines may be used, particularly meta-substituted derivatives. Examples are given of the production of phosphenyl chlorides, and acids in the form of salts, from dimethylaniline, and dimethyl- or diethyl-mtoluidine: sodium, potassium, calcium, copper, iron, and lead salts are described. Other dialkylamines which may be used are 3-chlor-dimethylaniline, 3-alkyloxy-dimethylaniline and tetramethyl-m-phenylenediamine. The products are of therapeutic value.ALSO:Copper, iron, and lead salts of the p-dialkylamino-arylphosphinous acids prepared from dialkylarylamines and phosphous trichloride, followed by hydrolysis with caustic alkali, are described. The salts of the acids from dimethylaniline and dimethyl- or diethyl-m-toluidine are mentioned.
