Dimethylaminophosphorus dichloride is an organophosphorus compound with the formula Me2NPCl2 (Me = methyl). A colorless liquid, it is a reagent in the preparation of other organophosphorus compounds. Many analogous compounds can be prepared from the reactions of secondary amines and phosphorus trichloride:[1]
