  Trifluoromethanesulfonic Hydrazides

  摘要：

  We succeeded to observe at low temperature in reactions of trifluoromethanesulfonic anhydride and trifluoromethanesulfonyl chloride with hydrazine, phenyl hydrazine, and 1,1-dimethylhydrazine a formation of the corresponding trifluoromethanesulfonic hydrazides that at heating to room temperature decomposed liberating nitrogen and affording trifluoromethanesulfinic acid. 2-Phenyl-2H-1,2,3-triazole-4-carboxylic hydrazide reacted with trifluoromethanesulfonic anhydride to furnish trifluoro-N'-(2-phenyl-2H-1,2,3-triazol-4-ylcarbonyl)methanesulfonic hydrazide that decomposed at heating with elimination of trifluoromethanesulfinic acid and nitrogen yielding 2-phenyl-2H- 1,2,3-triazole-4-carbaldehyde.

  1,2,3-三唑与三氟甲磺酰氯和三氟甲磺酸酐的反应

  摘要：

  Reactions of 4,5-dibromo-1,2,3-triazole, 1H-1,2,3-benzotriazole, and 2-phenyl-2H-1,2,3-triazole-4-carbonyl chloride with trifluoromethanesulfonyl chloride and trifluoromethanesulfonic anhydride were studied. 4,5-Dibromo-1,2,3-triazole sodium salt reacted with CF3SO2Cl in tetrahydrofuran to give 4,5-dibromo-2-(2-tetrahydrofuryl)-2H-1,2,3-triazole rather than expected 4,5-dibromo-2-trifluoromethylsulfonyl-2H-1,2,3-triazole. The latter was synthesized by treatment of 4,5-dibromo-1,2,3-triazole sodium salt with trifluoromethanesulfonic anhydride. The reaction of benzotriazole with (CF3SO2)(2)O afforded 1-trifluoromethylsulfonyl-1H-1,2,3-benzotriazole and 1,2,3-benzotriazolium trifluoromethanesulfonate. 2-Phenyl-2H-1,2,3-triazole-4-carbonyl chloride reacted with trifluoromethanesulfonamide sodium salt in DMF, yielding N-(dimethylaminomethylene)trifluoromethanesulfonamide. Possible ways for formation of the unexpected products were proposed.

  We describe a photocatalytic system that reveals latent photooxidant behavior from one of the most reducing conventional photoredox catalysts, N-phenylphenothiazine (PTH). This aerobic photochemical reaction engages difficult to oxidize feedstocks, such as benzene, in C(sp2)–N coupling reactions through direct oxidation. Mechanistic studies are consistent with activation of PTH via photooxidation and

  我们描述了一种光催化系统，该系统揭示了最具还原性的传统光氧化还原催化剂之一N-苯基吩噻嗪 ( PTH ) 的潜在光氧化行为。这种有氧光化学反应通过直接氧化在 C(sp 2 )-N 偶联反应中参与难以氧化的原料，如苯。机理研究与通过光氧化激活PTH和路易斯酸助催化剂清除在该过程中不可避免地形成的抑制剂一致。

  By revealing the robust photooxidant properties of phenalenyl-based organic Lewis acid, we have introduced this moiety as an effective organophotocatalyst for the oxidative azolation of unactivated and feedstock arenes. In addition to its tolerance for various functional groups and scalability, this photocatalyst was shown to be promising for the defluorinative azolation of fluoroarenes.

  photocatalysts, the hybrid photocatalysts reported here feature a reversible two-electron redox system with regular or inverted redox potentials for the two-electron transfer. The different oxidation states could be isolated and structurally characterized supported by NMR, EPR, and X-ray analysis. Mechanistic experiments employing time-resolved emission and transient absorption spectroscopy unambiguously

  描述了基于双阳离子吖啶鎓/卡宾杂化物的有机强氧化光催化剂的新设计概念。提出了此类杂化物的高度模块化合成，并且双阳离子在直接氧化C-N偶联中用作新型、定制的光氧化还原催化剂。在优化的条件下，苯甚至缺电子芳烃可以被氧化并与一系列N杂环偶联，每次催化转换产生一个低能光子，产率很高到极好，而常用的吖啶鎓光催化剂无法完成这一任务。具有挑战性的氧化步骤。与传统的光催化剂相比，本文报道的混合光催化剂具有可逆的双电子氧化还原系统，具有用于双电子转移的规则或反转的氧化还原电位。通过 NMR、EPR 和 X 射线分析，可以分离不同的氧化态并进行结构表征。采用时间分辨发射和瞬态吸收光谱的机械实验明确揭示了我们性能最佳的催化剂（+2.5 V vs SCE）的突出激发态潜力，并为机械关键步骤和中间体提供了证据。
