Pd‐catalyzed intermolecular dearomative Heck reaction of indoles with aryl iodides is described. The challenges on both reactivity and regioselectivity are addressed by the judicious regulation of the geometric and electronic properties of the substrates. An array of indoline derivatives bearing C2‐quaternary center is obtained in good to excellent yields (up to 93%) with exclusive regioselectivity
