General description

甲磺酸酐是一种有机化合物，通常用作制备甲基磺酸盐（甲磺酸盐）的试剂。它还用于使用各种胺前体合成甲磺酰胺。此外，甲磺酸酐和二甲基亚砜的混合物可以用作将伯醇和仲醇氧化为醛和酮的氧化剂。

Application

甲磺酸酐可用于在温和条件下将游离的半缩醛原位合成相应的甲磺酸糖酯。

Regioselective methanesulfonylation of simple aromatics using methanesulfonic anhydride can be achieved over zeolite catalysts. For example, methanesulfonylation of toluene over various cation-exchanged zeolite beta catalysts affords higher para-selectivity in the synthesis of methyl tolyl sulfone than standard Friedel-Crafts methanesulfonylation utilising

The utility of methanesulfonic anhydride for promoting the Friedel-Crafts acylation reaction of aryl and alkyl carboxylic acids is disclosed. This reagent allows the preparation of aryl ketones in good yield with minimal waste containing no metallic or halogenated components, clearly

Protic ionic liquids (PILs) are made by proton transfer from a Brønsted acid to a base and are of interest for their solvent and electrolyte properties such as high ionic conductivity. Unfortunately, many PILs have been misnamed, because their ionic
