Beschreibung

Allgemeine Beschreibung

Dimethylphosphoramidous dichloride (dimethylaminodichlorophosphine) is a phosphorus chloride derivative.[1] It exists in two stable isomers, a gauche-conformer with C₁ symmetry and anti-conformer with C_s symmetry.[2] Its synthesis has been reported.[3] Molecular conformation has been investigated through correlation between the ³⁵Cl NQR frequencies and charge on the chlorine atoms.[1] Its vibrational spectra has been studied.[4] Its reaction with SO₂ has been investigated.[5] It participates in the synthesis of [(dimethylamino)phosphoryl] bis(difluoromethylene)phosphonate.[6]

Anwendung
