  一系列含有不同芳族取代基和各种苄基离去基团（BR或N-芳基硼酸酯的+我3溴- ）已被合成。已经研究了取代基对其与H 2 O 2的反应性和甲基化醌（QM）形成的影响。NMR光谱和乙基乙烯基醚（EVE）捕获实验分别用于确定反应机理和QM形成。在硼酸酯的氧化裂解过程中不会产生QM，而是在生理条件下通过苯酚产物的后续转化产生的。吸电子取代基（例如芳族F，NO 2或苄基N ）促进了氧化脱硼+我3溴- ，而给电子取代基或更好的离去基团有利于QM产生。包含芳香族CH 3或OMe基团或良好离去基团（Br）的化合物可在生理条件下有效产生QM。最后，通过使用哈米特图建立了芳基硼酸酯的结构与活性之间的定量关系。现在可以预测地调整芳基硼酸/酯的反应性以及抑制或促进QM的形成。此调整很重要，因为某些应用程序可能会受益，而其他应用程序可能会受到QM生成的限制。

  N-甲氧基酰胺对铜催化有机三氟硼酸盐的亲电酰胺化

  摘要：

  据报道，使用N-甲氧基酰胺进行了铜催化的芳基三氟硼酸酯的亲电酰胺化反应。该反应显示出源自两个明显特征的高官能团相容性：1）N-甲氧基酰胺的高稳定性，以及2）在LiCl存在下的非碱性温和条件。所开发的方法还可以用于合成广泛分布于天然产物中的烯酰胺。初步的机理研究表明，第一步是在LiCl的协助下对三氟硼酸芳基酯进行金属转移，生成的芳基铜中间体通过非S N 2氧化添加至N-甲氧基酰胺并随后进行还原消除而提供了苯胺。

• Copper‐Catalyzed Electrophilic Amidation of Organotrifluoroborates with Use of <i>N</i> ‐Methoxyamides

  A copper‐catalyzed electrophilic amidation of aryltrifluoroborates with use of N‐methoxyamides is reported. The reaction shows high functional group compatibility derived from two distinct features: 1) the high stability of the N‐methoxyamides and 2) the nonbasic mild conditions in the presence of LiCl. The developed method can also be applied to the synthesis of enamides, which are widely distributed

  efficiently generate QMs under physiological conditions. Finally, a quantitative relationship between the structure and activity has been established for the arylboronic esters by using a Hammett plot. The reactivity of the arylboronic acids/esters and the inhibition or facilitation of QM formation can now be predictably adjusted. This adjustment is important as some applications may benefit and others
