The compound is prepared by treatment of phosphorus trichloride with diethylamine:
Illustrative of its utility is the synthesis of 1,2-bis(dichlorophosphino)benzene. The synthesis involves sequential lithiation of 1,2-dibromobenzene followed by treatment with (Et2N)2PCl:[1]
Finally, the amino substituents are removed using hydrogen chloride:
