tertiary amine and ketone components of 1‐carbonyl‐substituted anilines undergo [1,2] and [2,3] Stevens rearrangement reactions, triggered by a C4F9 radical, formed from electron donor–acceptor complexes. This approach enables the formation of a quaternary ammonium salt and thus a Stevens rearrangement to afford indolin‐3‐ones under mild conditions.
1-羰基取代的苯胺的叔胺和酮组分经历由电子供体-受体配合物形成的C 4 F 9自由基引发的[1,2]和[2,3] Stevens重排反应。这种方法可以形成季铵盐,从而进行史蒂文斯重排,从而在温和的条件下提供吲哚-3-酮。
