• An Aminative Rearrangement of <i>O</i> ‐(Arenesulfonyl)hydroxylamines: Facile Access to <i>ortho</i> ‐Sulfonyl Anilines

  An aromatic rearrangement of hydroxylamine derivatives that leads directly to ortho-sulfonyl anilines from simple starting materials is reported. This is achieved through formation of a new C−N bond with excellent levels of regiocontrol for the ortho isomer(s), which is proposed to be the result of attractive non-covalent interactions occurring during the C−N bond-forming step.

  据报道，羟胺衍生物的芳族重排可从简单的起始原料直接生成邻磺酰基苯胺。这是通过形成新的 CN 键来实现的，该键对邻位异构体具有出色的区域控制水平，这被认为是在 CN 键形成步骤中发生有吸引力的非共价相互作用的结果。
