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.

Bentonite K10 clay has been used to catalyze the formation of enamino carbonyl derivatives, 2-methyl-1H-benzimidazoles, Hantzsch 1,4-dihydropyridines, Hantzsch pyridines, 2-substituted 1,3-diphenylimidazolidines, and tetrahydropyranylbenzazoles.
