| Abstract: | The reaction of dibutyltin oxide with benzenesulfonic acid or methylsufonic acid gave two new dibutyltin(IV) sulfonates which can be used as the catalysts for the synthesis of acetals and ketals. The opti-mal reaction conditions were obtained by orthogonal experiments. The advantages of the present procedure are high yields and short reaction time. Furthermore, the catalysts could be recovered easily by filtration and reused efficiently. |
