  Azo compounds (RN = NR′) are an important class of organic molecules that find wide application in organic synthesis. Herein, we report an efficient, practical and metal-free oxidation of hydrazines (RNH-NHR’) to azo compounds using 5 mol% HBr and hydrogen peroxide as terminal oxidant. This new method has been demonstrated by 40 examples with excellent yields. In addition, we showcased two examples

  作者：Min Hye Kim、Jinho Kim

  日期：2018.2.2

  various fruitful organic reactions such as a catalytic Mitsunobu reaction were reported by virtue of alkyl 2-phenylazocarboxylates, however, the synthesis of alkyl 2-phenylazocarboxylates largely depended on the stoichiometric use of toxic oxidants. In this manuscript, an environment-friendly aerobic oxidative transformation of alkyl 2-phenylhydrazinecarboxylates to alkyl 2-phenylazocarboxylates is

  近来，由于2-苯基偶氮羧酸烷基酯，报道了各种富有成效的有机反应，例如催化的Mitsunobu反应，但是，2-苯基偶氮羧酸烷基酯的合成很大程度上取决于有毒氧化剂的化学计量使用。在该手稿中，公开了一种环境友好的2-苯基肼甲酸烷基酯的好氧氧化转化为2-苯基偶氮羧酸烷基酯的方法。在温和条件下，使用CuCl和DMAP系统可有效催化2-苯基肼甲酸烷基酯的需氧氧化。本发明的铜催化反应速率比以前报道的铁催化速率快得多，并且在3小时内合成了多种偶氮产物。本协议在更大范围内是有效的。

  are rare amphoteric reagents with high, but underdeveloped synthetic potential. Herein, we study the formation of indazolones by Friedel–Crafts cyclization of N-isocyanates using blocked (masked) N-isocyanate precursors: the effect of the masking group and the reaction scope have been delineated. Substrate synthesis has also been improved using a reported copper-catalyzed coupling of arylbismuth(V) reagents

  氮取代的异氰酸酯（N-异氰酸酯）是罕见的两性试剂，具有很高的合成潜力，但开发潜力不大。在本文中，我们研究了使用封端的（被掩蔽的）N-异氰酸酯前体通过Friedel-Crafts对N-异氰酸酯的环化形成吲哚酮的作用：已经描述了掩蔽基团的作用和反应范围。使用已报道的与半不稳定的OPh封端基团兼容的芳基铋（V）试剂的铜催化偶联也可以改善底物的合成。
