Description

Description générale

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.

Application

Dimethylphosphoramidous dichloride (N,N-dimethylamidodichlorophosphite) may be used in the synthesis of the following:

• N,N-dimethylamidotetrachlorophosphorane
