  transition-metal-free cross-coupling of sulfonyl hydrazides with benzyl ammonium salts has been developed to synthesize benzyl sulfones using Cs2CO3 as base under mild conditions. The protocol employs stable and easy to handle coupling partners, and is endowed with good substrate compatibility, leading to functional benzyl sulfones in good yields.

  已经开发出一种实用且有效的方法，该方法采用磺酰肼与苄基铵盐的无过渡金属交叉偶联，以Cs 2 CO 3为碱，在温和条件下合成苄基砜。该方案使用稳定且易于操作的偶联伙伴，并具有良好的底物相容性，从而可以高收率生产功能性苄砜。

  The Fe-catalyzed decomposition of sulfonylhydrazones gives rise to sulfones. The reaction is quite general and allows the preparation of sulfones from a variety of aryl, alkyl, and α,β-unsaturated aldehydes and ketones. Crossover experiments reveal that the reaction is an intermolecular process, which may proceed by nucleophilic attack of the sulfinate anion on an iron carbene complex.

  磺酰腙的Fe催化分解产生砜。该反应非常普遍，允许从各种芳基、烷基和 α,β-不饱和醛和酮制备砜。交叉实验表明，该反应是一个分子间过程，可以通过亚磺酸根阴离子对铁卡宾配合物的亲核攻击来进行。
• Base and solvent mediated decomposition of tosylhydrazones: highly selective synthesis of N-alkyl substituted hydrazones, dialkylidenehydrazines, and oximes

  Base and solvent mediated decomposition of tosylhydrazones was studied. It was found that reaction of tosylhydrazones in CH3NO2 in the presence of 1 equiv of K2CO3 in 90 degrees C gave N-alkylated products in 52-96% yield. However, when the same reaction was carried out in mixed solvent of CH3NO2 and dioxane in the presence of 3 equiv of NaOH at 110 degrees C, dialkylidenehydrazines were obtained in moderate to high yield. If the reaction was carried out in mixed solvent of CH3NO2 and DMSO in the presence of 10 equiv of NaOH at 110 degrees C, CH3NO2 can act as the precursor of hydroxylamine and corresponding oximes were formed in up to 92% yield.
