Abstract

Neat chlorosulfonic acid reacts with anhydrous sodium tungstate to givetungstate sulfuric acid (TSA), a new dibasic inorganic solid acid in which two sulfuricacid molecules connect to a tungstate moiety via a covalent bond. A variety of oximeswere oxidized to their parent carbonyl compounds under mild conditions with excellentyields in short times by a heterogeneous wet TSA/KMnO4 in dichloromethane system.
