It would appear from the foregoing descriptions of the reactions of benzene with phosphorus trichloride to produce phenylphosphine dichloride and of benzene with phenylphosphine dichloride to produce diphenylphosphine chloride that it would be possible to react benzene with phosphorus trichloride to produce diphenylphosphine chloride with or without mixture with phenylphosphine dichloride. However, this is not readily accomplished. The reaction of the benzene and the phosphorus trichloride is faster than the reaction of the benzene with the phenylphosphine dichloride as mentioned previously in connection with the reaction temperatures to be employed. Thus, reaction of the benzene with phenylphosphine dichloride does not occur as long as any phosphorus trichloride remains in the reaction mixture.
