The reaction of pentafluorophenol, 2,2,3,3-tetrafluoropropyl alcohol, and 2,2,3,3,4,4,5,5-octafluoropentyl alcohol with carbon tetrachloride in the presence of aluminum chloride were investigated.The main products from the reaction of pentafluorophenol with these reagents are pentafluorophenoxytrichloromethane, di(pentafluorophenol) carbonate, and tri(pentafluorophenoxy)chloromethane.The ratios of the products depend on the reaction conditions.The use of a large excess of carbon tetrachloride leads to the preferential formation of pentafluorophenoxytrichloromethane.The addition of water promotes the formation di(pentafluorophenyl) carbonate.When heated with carbon tetrachloride and aluminum chloride and subsequently treated with water, 2,2,3,3-tetrafluoropropyl and 2,2,3,3,4,4,5,5-octafluoropentyl alcohols are converted into di(2,2,3,3-tetrafluoropropyl) carbonate and di(2,2,3,3,4,4,5,5-octafluoropentyl) carbonate respectively.
