【Abstract】 This paper reports a new convenient method for preparing anhydrous SnCl₄ with SnCl₄·H₂O crystal and dichlorosulfoxide as starting materials. The product is used in heterogeneous Diels-Alder and Phenol formylation reactions. The results show that the anhydrous SnCl₄ prepared by refluxing in the presence of SOCl₂ have good effects on these reactions.更多还原
