  Diazo Preparation via Dehydrogenation of Hydrazones with “Activated” DMSO

  摘要：

  We report that "activated" dimethyl sulfoxide efficiently dehydrogenates hydrazones to the respective diazo species at -78 degrees C. Under optimized conditions, triethylamine hydrochloride is removed quantitatively by vacuum filtration to provide solutions of diazo compounds. Stable diazo species can be isolated in high yield, or alternatively, the direct treatment of these solutions with carboxylic acids provides esters.

• Reaction of Hydrazones with Methoxy(tosyloxy)iodobenzene (MTIB): Tosylate Formation under Oxidative Conditions
  作者：Christopher Ramsden、Helen Rose

  DOI：10.1055/s-1997-702

  日期：——

  Treatment of aromatic hydrazones 1 containing electron-withdrawing, reduction sensitive substituents with MTIB gives the corresponding tosylates 2 in high yield. When the tosylate is particularly reactive the thermodynamically more stable methyl ether 3 is isolated. Analogous reactions with DAIB give acetates 4 in high yield. Dialkyl hydrazones give olefinic products (e.g. 7 and 8). (+)-Camphor hydrazone 1k with either MTIB or DAIB gives both camphene 12 (major product) and tricyclene 11 (minor product) suggesting that a carbene pathway accounts for some of the material formed in these oxidations.

  含有吸电子、还原敏感取代基的芳香腙1与MTIB反应，可高效地得到相应的甲苯磺酸酯2。当甲苯磺酸酯具有特别高的反应活性时，则会分离得到热力学上更稳定的方式形成的甲醚3。类似地，与DAIB反应可高效地得到乙酸酯4。二烷基腙则生成烯烃产物（例如7和8）。(+)-樟脑腙1k与MTIB或DAIB反应，会同时生成荻烯12（主要产物）和三环烯11（次要产物），表明在这些氧化反应中，卡宾路径可能用于形成一部分反应产物。
