Triphenylphosphine → 2,6-Dichlorophenol

Participants

Reaction Steps

236 g (1 mol) of 2,2,6,6-tetrachlorocyclohexanone and 2.5 g (0.01 mol) of triphenylphosphine were introduced into a reactor equipped with a stirrer and a condenser. The mixture was heated at 150°-180° C. under stirring; the reaction was terminated when the evolution of hydrogen chloride from the reaction mixture ceased. The reaction mixture was then distilled under reduced pressure (boiling point (20 mm Hg)=100° C.) to yield 137.5 g of 2,6-dichlorophenol.
