DIMETHYLPHOSPHORAMIDOUS DICHLORIDE Usage And Synthesis

Chemical Properties	Colorless to light yellow liquid
Uses	Dimethylphosphoramidous dichloride (N,N-dimethylamidodichlorophosphite) may be used in the synthesis of the following N,N-dimethylamidotetrachlorophosphorane, O-propylchloroformimino-N,N-dimethylamidochlorophosphate, bisarylsulphonyldiazadiphosphetidines.
Uses	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
General Description	Dimethylphosphoramidous dichloride (dimethylaminodichlorophosphine) is a phosphorus chloride derivative. It exists in two stable isomers, a gauche-conformer with C₁ symmetry and anti-conformer with C_s 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.
