A metal‐free synthesis of diversified benzimidazoles from N‐arylamidines through a phenyliodine(III) diacetate (PIDA) promoted intramolecular direct C(sp2)H imidation has been developed. The reaction proceeds smoothly at 0 °C or ambient temperature to provide the desired products in good to excellent yields. The synthesis of 2‐alkyl‐ or 2‐alkyl‐fused benzimidazoles, which are generally inaccessible
