An efficient palladium-catalyzed reaction of 2-iodostyrenes with di-t-butyldiaziridinone provides indoles via a simultaneous installation of two C-N bonds. The reaction likely proceeds through an oxidative insertion of Pd to aryl iodide and subsequent vinyl C-H activation to from a pallada(II)cycle intermediate, which is bisaminated by di-t-butyldiaziridinone.
