n–carboxylation of 2‐alkynylanilines with carbondioxide in the presence of dimethylzinc (ZnMe2) and cesium fluoride (CsF) for the effective synthesis of indolyl‐3‐carboxylic acids and indolodihydropyran‐2‐one is described. Through a mechanistic study, it is unveiled that the metal ions Cu2+, Zn2+, Cs+ and F− are working together for this CO2‐based highly efficient carboxylation.
