  摘要：

  描述了卤化铝对酰胺、磺酰胺和酰基磺酰胺的 C-N 键的化学选择性裂解。AlCl 3和AlI 3显示出对N-烷基和N-酰基部分的互补反应性。N-烷基酰基磺酰胺、仲N- (叔丁基)磺酰胺和叔N- (叔丁基)酰胺在用由铝和碘在乙腈中原位生成的AlI 3处理后发生N-脱烷基化。相反，AlCl 3优先裂解叔和仲磺酰胺的N-酰基。

• Regioselective Ortho Olefination of Aryl Sulfonamide via Rhodium-Catalyzed Direct C–H Bond Activation
  作者：Weijia Xie、Jie Yang、Baiquan Wang、Bin Li

  日期：2014.9.5

  Rh(III)-catalyzed ortho C–H olefination of aryl sulfonamide directed by the SO2NHAc group is reported. This oxidative coupling process is achieved highly efficiently and selectively with a broad substrate scope. The reactions of N-tosylacetamide with acrylate esters afford ortho-alkenylated benzofused five-membered cyclic sulfonamides, whereas styrenes provide the direct diolefination products.

  据报道，Rh（III）催化了由SO 2 NHAc基团引导的芳基磺酰胺的邻位C-H烯基化反应。这种氧化偶联过程可以在广泛的基材范围内高效高效地进行。N-甲苯磺酰基乙酰胺与丙烯酸酯的反应提供了邻链烯基化的苯并稠合的五元环磺酰胺，而苯乙烯提供了直接的二烯化产物。

  Abstract Sulfonamides were converted to the corresponding N‐acyl sulfonamides with carboxylic acid chlorides and anhydrides in the presence of silica chloride. All reactions were performed in both heterogeneous and solvent‐free conditions. This method provides the N‐acyl sulfonamides products in good to high yield and purity.

  Silica sulfuric acid catalyzes efficiently the reaction of sulfonamides with both carboxylic acid anhydrides and chlorides under solvent-free and heterogeneous conditions. All the reactions were done at room temperature and the N-acylsulfonamides were obtained with high yields and purity via an easy work-up procedure. This method is attractive and is in a close agreement with green chemistry. These

  from aldehydes by an iron-catalyzed nitrene insertion reaction has been developed. Both aryl and aliphatic aldehydes can directly afford the corresponding amides with an iron(II)-terpyridine (tpy) complex formed in situ as catalyst, and PhI=NTs as nitrogen source under mild reaction conditions. An ESI-MS study revealed the formation of [Fe(tpy) 2 (NTs)] 2+ as a reaction intermediate.

  已经开发了一种通过铁催化的氮烯插入反应从醛构建酰胺化合物的简便方法。在温和的反应条件下，芳基和脂肪醛都可以直接得到相应的酰胺，以原位形成的铁（II）-三联吡啶（tpy）配合物作为催化剂，PhI=NTs作为氮源。ESI-MS 研究揭示了 [Fe(tpy) 2 (NTs)] 2+ 作为反应中间体的形成。
