2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) catalyzes the preparation of N-tetrahydropyranylbenzazoles, 2-substituted 1,3-diphenylimidazolidines, and N-(arylmethylene)benzene-1,2-diamines. In the latter case, use of one equivalent of DDQ provides a novel one-pot method for the synthesis of 1H-benzimidazoles.
2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)催化N-四氢吡喃基苯并恶唑,2-取代的1,3-二苯基咪唑烷和N-(芳基亚甲基)苯-1,2-二胺的制备。在后一种情况下,使用一当量的DDQ提供了一种新颖的一锅法,用于合成1 H-苯并咪唑。
