  Synthesis and reactivity of polyfluorinated fluorosulfatocarbinols in the presence of bases

  摘要：

  Compounds CF3CR(OH)CF2OSO2F (I) (R = MeO, Ph) were synthesized by the reaction of alpha-(fluorosulfato)pentafluoroacetone with MeOH or C6H6/AlCl3. In the presence of bases compound (I), depending on the reaction conditions, forms either cyclic sulfates or products of their isomerization - substituted alpha-fluorosulfato-trifluoropropionic acid fluorides which are capable of nucleophilic substitution of FSO3 groups in reaction with the nucleophiles.
