1. Amides of phenylvinylphosphinic acid and the ethyleneimide of phenyl-β-chloroethylphosphinic acid were produced. 2. The IR spectra of the substances obtained were studied. On the basis of the values of the frequencies of the P=O and C=C groups, the presence of pπ-dπ-conjugation in the systems considered was hypothesized. 3. The rate of inversion of nitrogen in the ethyleneimides of phenylvinylphosphinic and phenyl-β-chloroethylphosphinic acids, according to the PMR data, is very high.
