Rearrangements of various vicinal diols (1a–f) induced by hexachloroantimonate aminium salts A or B were found to occur in a similar manner when antimony pentachloride was used instead of aminium salts. Antimony pentachloride is proposed as the active catalytic species, possibly deriving from the oxidation of the hexachloroantimonate anion SbCl6– by the aminium counterpart. (© Wiley-VCH Verlag GmbH
