Air‐ and bench‐stable N ‐cyano‐ N ‐phenyl arenesulfonamides (NCASs) have been demonstrated to be sulfonylating agents for the synthesis of N ‐arylsulfonyl benzimidazoles catalyzed by dicobalt octacarbony, Co 2 (CO) 8 , without any bases. This protocol undergoes an intermolecular N ‐ to N ‐arylsulfonyl transfer process involving the S−N bond cleavage of NCASs instead of normal CN group migration via the C−N bond scission.
