The C3-arylation of C2-substituted indoles using Barton's protocol is investigated. The reaction is performed using triarylbismuth bis(trifluoroacetates) and is catalyzed by copper bis(trifluoroacetate). The reaction operates under mild conditions, shows excellent substrate scope, and demonstrates good function group tolerance. Electron neutral or poor aryl groups substituted at any position are efficiently
