Diphosphorus tetrachloride is an inorganic compound with a chemical formula P2Cl4. It is a colorless liquid that decomposes near room temperature and ignites in air.[1]

Production

It was first prepared in 1910 by Gauthier by the following reaction:

2 PCl3 + H2 → P2Cl4 + 2 HCl

An improved method involves coevaporation of phosphorus trichloride and copper, as described by the following:[1]

2 PCl3 + 2 Cu → P2Cl4 + 2 CuCl

Reactions

Near room temperature, the compound degrades to give phosphorus trichloride and an ill-defined phosphorus monochloride:

P2Cl4 → PCl3 + 1/n [PCl]n

The compound adds to cyclohexene to give trans-C6H10-1,2-(PCl2)2.[1]
