摘要
A novel and efficient synthesis of benzoxazole and benzimidazole derivatives via 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.
