Diphosphorus tetrachloride is an inorganic compound with a chemical formula PCl. It is a colorless liquid that decomposes near room temperature and ignites in air. Production. 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: Reactions. Near room temperature, the compound degrades to give phosphorus trichloride and an ill-defined phosphorus monochloride: The compound adds to cyclohexene to give "trans"-CH-1,2-(PCl).
