摘要:
alpha-Chloropolyfluoroalkyl ethers were synthesized by the reaction of polyfluorinated alcohols H(CF(2)CF(2)) (n) CH(2)OH (n=1-3) with aliphatic aldehydes (ethanal, propanal, butanal) and hydrogen chloride. Yield of alpha-chloroethers decreases from 71 to 61% as the number of carbon atoms in the starting reactants increases. alpha-Chloropolyfluoroalkyl ethers react with polyfluorinated alcohols (n = 1-3) to form acetals in yield of up to 40-61%, and with methanol and ethanol, up to 98%.
