A solution of 10 g. (0.08 mole) of diethylphosphinous chloride in 100 ml. of ether was added to a solution of p-chlorophenyllithium [prepared from 15.4 g. (0.08 mole) of p-chlorobromobenzene in 100 ml. of ether and 54 ml. of 1.5M n-butyllithium in hexane] under a nitrogen atmosphere. After 30 minutes, the reaction mixture was quenched with a few drops of ethyl acetate and the solvent was removed at reduced pressure. Distillation of the residual oil gave (p-chlorophenyl) (diethyl)phosphine, b.p. 86°-89° C. at 1.5 mm.
