Simply aqueous sodium hydroxide is sufficient to exclude ionic side reactions and to prepare 2‐aminobiphenyls from aryl diazotates and anilines through a new variant of the Gomberg–Bachmann reaction (see scheme). The metal‐free reaction under basic conditions allows to exploit the highly radical‐stabilizing effect of the aniline's free amino function for the first time, which leads to a so far unreached
仅用氢氧化钠水溶液就足以排除离子副反应,并通过Gomberg-Bachmann反应的新变体从芳基重氮酸酯和苯胺制备2-氨基联苯(参见方案)。在碱性条件下的无金属反应允许首次利用苯胺的游离氨基官能团的高度自由基稳定作用,从而导致迄今未达到的区域选择性。
