Abstract
By treatment at pH 9.5, starting from sulfonylurea (1f) (Rimsulfuron®), the diheteroaryl amine (3) is exclusively obtained, whereas under the same conditions sulfonylureas (1a-e) showed only cleavage of the SO2-NH bond. A reaction mechanism proceeding through a five-membered transition state was strongly suggested by both semiempirical and ab initio molecular orbital calculations.
