route of oxidative amination of benzoxazole by activation of C–H bonds with secondary or primary amines in the presence of catalytic iodine in aqueous tert-butyl hydroperoxide proceeds smoothly at ambient temperature under neat reaction condition to furnish the high yield of the aminated product. This user-friendly method to form C–Nbonds produces tertiary butanol and water as the byproduct, which are
