A dehydrogenative [3 + 2] annulation reaction of aniline derivatives and alkenes has been developed via the ruthenium-electron catalytic systems for the synthesis of versatile indolines. Electricity is used as a sustainable oxidant to regenerate the active Ru(II) catalyst and promote H evolution. This protocol is ecofriendly and easy to handle as it uses a simple undivided cell in mild conditions without the employment of metal oxidants.
通过钌电子催化体系,开发了一种苯胺衍生物与烯烃的脱氢[3 + 2]环化反应,用于合成多功能吲哚啉。电被用作可持续氧化剂,以再生活性Ru(II)催化剂并促进氢气释放。该方法环保且易于操作,因为它在温和条件下使用简单的无隔膜电池,无需使用金属氧化剂。
