Abstract Unlike the saturated aliphatic and aromatic alcohols, allyl alcohol under the same conditions reacts with polyfluoroalkyl chlorosulfites to form not ethers, but polyfluorinated alcohols. The exception is polyfluoroalkyl chlorosulfites with the chain length of more than five carbon atoms. Allyl ethers of polyfluorinated alcohols of general formula CH 2= CHCH 2 OCH 2 (CF 2 CF 2) n H (n= 1–3) were obtained, when the reaction proceeded in the ...
