本文报道了苯胺衍生物与烯烃在阳离子-电子催化体系中的[3 + 2]成环反应，并合成了多用途的吲哚啉。电被用作可持续的氧化剂来再生活性Ru（II）催化剂并促进H2析出。该方案是生态友好且易于处理的，因为它在温和条件下使用简单的未分开的电池，而不使用金属氧化剂。
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 H2 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.
