Carbonylcompounds are successfully converted into oxathioacetals and dithioacetals with 2-mercaptoethanol and ethane-1,2-dithiol using a catalytic amount of iron(iii) fluoride under solvent-free conditions. The catalysts were recovered and reused in various runs without affecting the efficiency of the process.

The novelionicliquid with multi‐SO3H groups has been synthesized through the simple procedure and its catalytic activity for the oxathioacetalization was investigated carefully at room temperature under solvent‐free condition. The results showed that the novelionicliquid was very efficient for the reactions with the average yields over 90%. Mild reaction conditions, high yields, small amount of
