The latter reactions are exemplified by the cleavage of δ-valerolactone with zinc chloride and thionyl chloride to produce 5-chlorovaleryl chloride, reaction of that acid chloride with diazomethane, followed by treatment of the resulting diazomethylketone with hydrochloric acid to yield 1,6-dichloro-2-hexanone, and reaction of that ketone with triphenylphosphine to afford (6-chloro-2-oxohexyl) triphenylphosphonium chloride. This product is converted to (5-chloropentanoylmethylene)triphenyl phosphorane by reaction with aqueous sodium hydroxide.
