Reaction Steps
A solution of 20 parts of (6-chloro-2-oxo-hexyl)-triphenylphosphonium chloride in 200 parts of water is made alkaline by the addition of a 50% aqueous sodium hydroxide solution and extracted with benzene. The combined organic extracts are dried over anhydrous sodium sulfate, then stripped of solvent under reduced pressure to afford (5-chloropentanoylmethylene) triphenylphosphorane.
