Conclusions

  1. 1.

    A study was made of the fragmentation under electron impact of the previously unknown derivatives: 2,2,5,5-tetramethylpyrrolidine-1-oxyl-3-amidodiethyleneimidothiophosphoric acid and 2,2,6,6-tetra-methylpiperidine-1-oxyl-4-amidodiethyleneimidothiophosphoric acid.

     
  2. 2.

    A mechanism was proposed for the decomposition of the molecular ions of paramagnetic derivatives of ethylenephosphoramides.

     
  3. 3.

    We were the first to synthesize some spin-labeled derivatives of ethylenephosphoramides.
