Dialkylamides of diphenylphosphinoylacetic acids, dialkylaminomethyl-substituted by the methylene group, were prepared by means of the Mannich reaction from diphenyl(dialkylcarbamoylmethyl)-phosphine oxides or by reaction of the latter compounds with tetraethylmethylenediamine. Extractive ability of the obtained compounds toward U(VI) and Pd(II) in nitrate media was studied.
