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
The complex [(dppb)Pt(µ-OH)]2(BF4)2 displays high catalytic activity in the thioacetalization of a variety of aldehydes and ketones with mercaptoethanol under very mild conditions. The reaction rate is greatly enhanced by the addition to the reaction mixture of magnesium perchlorate as drying agent and molar turnovers as high as 9700 can be observed. The effect of different desiccating agents is also
