Organophosphorus derivatives of ethylenemine 2. Addition to dialkylphosphorousacid-ethyl eneamides of halogenated hydrocarbons and of halogens

Summary

• 1. β-Chloroethylmethylarylamides of dialkylphosphoric acids were obtained by addition of halogenated hydrocarbons to ethyleneamides of dialkylphosphoric acids. The addition reaction is shown to proceed with rupture of the ring.

• 2. Addition of chlorine to ethyleneamides of dialkylphosphoric acids gave a series of β-chloroethylchloramides of dialkylphosphoric acids.

• 3. It is shown: a) that the synthesized chloramides undergo the Arbuzov rearrangement in the normal direction; b) the chloramides add on to ethyleneamides of dialkylphosphoric acids with formation of symmetrical bisdi-alkylphosphono-di-β-chloroethylhydrazines.
