  A simple and rapid method for efficient synthesis of sulfonyl chlorides/bromides from sulfonyl hydrazide with NXS (X = Cl or Br) and late-stage conversion to several other functional groups was described. A variety of nucleophiles could be engaged in this transformation, thus permitting the synthesis of complex sulfonamides and sulfonates. In most cases, these reactions are highly selective, simple

  描述了一种使用 NXS（X = Cl 或 Br）从磺酰肼高效合成磺酰氯/溴化物并在后期转化为几个其他官能团的简单快速方法。多种亲核试剂可以参与这种转化，从而可以合成复杂的磺酰胺和磺酸盐。在大多数情况下，这些反应具有高度选择性、简单且清洁，以优异的产率提供产品。

  Arene- and alkanesulfonamides were prepared by treatment of the corresponding sodium sulfonates with triphenylphosphine dibromide or dichloride followed by amines in the presence of triethylamine via sulfonyl halides. Reactions of sodium aminosulfonates gave cyclized products. Amidation of p-toluenesulfonic acid with triphenylphosphine dichloride was also examined to give N-benzyl-p-toluenesulfonamide. Methyl p-toluenesulfonate was obtained by esterification of sodium p-toluenesulfonate via p-toluenesulfonyl chloride.
