3‐Phosphinoylindoles are important components of biological active natural products and materials in pharmaceuticals. Herein, a new approach for the synthesis of 3‐phosphinoylindoles has been established by a Rh(III)‐catalyzed cyclization from readily accessible (2‐azidostyryl)diphenylphosphine oxides. This intramolecular transformation occurs through a unique phosphine oxide group migration and offers a straightforward
