Abstract
1. A convenient method was proposed for obtaining ethylα-aminobenzylphenylphosphinate from hydrobenzamide and ethyl phenylphosphinate. It was found that this reaction is stereo-specific as regards the configuration of the C and P atoms. 2. The first members ofα-aminophosphinic acids, and specificallyα-aminobenzylphenyl-phosphinic acid and its ethyl ester, were obtained in the optically active form, and the absolute configurations of the asymmetric C and P atoms were determined. 3. The rate of hydrolyzing ethylα-aminobenzylphenylphosphinate by dry HBr was studied, 4. Sorbents of the polystyrene type, containing the groupings of R-α-aminobenzyl-phenylphosphinic acid and its ethyl ester, were obtained for the first time.
