This article describes the first application of 2-aminophenylboronates as precursors for benzynes. Utilizing Rh₂(HNCOCF₃)₄ as the catalyst, Rh(II)-nitrene-mediated N–H amination of the starting material triggered a cascade of oxidation/elimination processes resulting in the generation of benzynes, thus providing suitable conditions for a one-pot cycloaddition with azides or furans. The transformation proceeded under acid-, base-, and fluoride-free conditions, below ambient temperature, and was applicable to a range of substrates containing glycoside and nucleoside moieties, as well as silyl-functional groups.

通过Rh（II）催化的NH胺化/氧化/消除级联过程从2-氨基苯基硼酸酯中一锅生成苯炔

本文介绍了2-氨基苯基硼酸酯作为苯炔的前体的首次应用。利用Rh ₂（HNCOCF ₃）₄作为催化剂，Rh（II）-丁二烯介导的N-H氨化反应引发了一系列的氧化/消除过程，从而生成了苯并炔，因此为一个化合物提供了合适的条件。锅与叠氮化物或呋喃的环加成反应。转化在环境温度以下，无酸，无碱和无氟的条件下进行，适用于一系列包含糖苷和核苷部分以及甲硅烷基官能团的底物。
