Organische Phosphorverbindungen 39. Methoden zur Herstellung von Chloräthylphosphonsäuredichlorid,ClCH2CH2P(O)Cl2 und CH3CHClP(O)Cl2 [1]

It is shown that the KINNEAR -PERREN reaction with ClCH₂CH₂Cl, PCl₃, and AlCl₃ produces the two possible isomers ClCH₂CH₂P(O)Cl₂ and CH₃CHClP(O)Cl₂. Methods for the preparation of pure ClCH₂CH₂P(O)Cl₂ and pure CH₃CHClP(O)Cl₂ are described. The physical properties of a number of chloroethyl groups containing phosphorus compounds are listed.
