(4-Methylphenyl)sulfonyl acetate 化学特性,用途語,生産方法
純化方法
The most likely impurity is p-toluenesulfonic acid (could be up to 10%). This can be removed by dissolving it in dry Et2O and cooling until the anhydride crystallises out. It decomposes on heating; below ~130o it gives the disulfonic anhydride and above ~130o polymers are formed, but it can be distilled in a vacuum if it is free of acid. It is used for cleaving ethers [Prep, IR, NMR: Karger & Mazur J Org Chem 36 528, Karger & Mazur J Org Chem 36 532 1971]. [Beilstein 11 III 255.]
