A highly effective silver(I)-mediated C-H amination of 2-alkenylanilines has been developed to afford a diverse range of substituted indoles. High functional group tolerance, broad substrate scope, simple/fast/high-yielding reaction, and recovery/reuse of the inexpensive silver oxidant are noteworthy. Furthermore, an uncommon migratory process of beta-monosubstituted 2-alkenylanilines with solvent-dependence was demonstrated.
