A regioselective synthesis of indoles from arylhydrazine hydrochlorides with alkynes and diethyl ketone catalyzed by a rhodium complex is described. A possible mechanism involving an in‐situ generated oxidizing directing group NNCR1R2 assisted ortho‐CHactivation and reductive elimination are proposed. The catalytic reaction is highly compatible with a wide range of functional arylhydrazines and
