A novel and efficient synthesis of benzoxazole and benzimidazolederivativesvia a ligand‐free, copper(I)‐catalyzed, one‐pot cascade process has been developed. A variety of carbodiimides coupled with o‐halophenols or o‐haloanilines to give the products in moderate to excellent yields under the mild conditions.
