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]
It was first prepared in 1910 by Gauthier by the following reaction:
An improved method involves coevaporation of phosphorus trichloride and copper, as described by the following:[1]
Near room temperature, the compound degrades to give phosphorus trichloride and an ill-defined phosphorus monochloride:
The compound adds to cyclohexene to give trans-C6H10-1,2-(PCl2)2.[1]
