Ring-opening of steroidal 2,3-epoxides with thiols can be carried out effectively in the Brønsted acidic ionic liquid [Hmim] +[BF4]- as a recyclable solvent and catalyst. The use of other ionic liquids/molten salts resulted in a decrease in the conversion and/or in reduced selectivity. In [bmim]+Br-, a conversion of 2,3epoxy-17-ones into 2,17- and 3,17-diones was also observed.
