Procedure

158 parts of diisopropoxyphenylphosphine are added slowly to 84 parts of pivaloyl chloride at 50°-60° C., with thorough stirring. Stirring is then continued for two hours, after which the mixture is fractionated under reduced pressure. Isopropyl pivaloyl-phenylphosphinate distils at 119°-121° C./0.5 mm.
