Allgemeine Beschreibung

Dimethylphosphoramidous dichloride (dimethylaminodichlorophosphine) is a phosphorus chloride derivative. It exists in two stable isomers, a gauche-conformer with C1 symmetry and anti-conformer with Cs symmetry. Its synthesis has been reported. Molecular conformation has been investigated through correlation between the 35Cl NQR frequencies and charge on the chlorine atoms. Its vibrational spectra has been studied. Its reaction with SO2 has been investigated. It participates in the synthesis of [(dimethylamino)phosphoryl] bis(difluoromethylene)phosphonate.

Anwendung

Dimethylphosphoramidous dichloride (N,N-dimethylamidodichlorophosphite) may be used in the synthesis of the following:
  • N,N-dimethylamidotetrachlorophosphorane
  • O-propylchloroformimino-N,N-dimethylamidochlorophosphate
  • 1,3-bisarylsulphonyl-1,3,2,4-diazadiphosphetidines
