Several Hantzsch dihydropyridine derivatives were synthesized and applied to the reaction. Other 4,4-dihydro derivatives afforded the reduction products, but the yields were slightly lower than that of 1a. 4-Substituted (alkyl or aryl) Hantzsch dihydropyridines did not react under the conditions

The by-products included 2-phenyl- and 1-benzyl-2-phenylbenzimidazoles. In the presence of molecular oxygen, the yields of these compounds increased, and the results were applied to the synthesis of 2-arylbenzimidazole derivatives; see:
