Heterocyclic moieties, such as benzimidazole, are examples of important nuclei that have found widespread use in a variety of scientific subfields, such as medical and applied chemistry. In this study, we described the photocatalytic synthesis of numerous different benzimidazole derivatives using a solid-state acid composed of zirconium oxosulfate embedded into carbon (ZrOSO4@C). A metal-organic framework

A highly efficient synthesis of 2-aminoquinoxalines has been developed via the one-pot two-step cyanide-mediated sequential reactions of ortho-phenylenediamines with aldehydes under aerobic oxidation conditions. A variety of substrates, including aliphatic aldehydes bearing acidic a-protons, are applicable to this protocol and afford the desired 2-aminoquinoxalines in high yields.

A one-pot condensation of an aldehyde with 1,2-phenylenediamine or 2-aminothiophenol in dimethyl carbonate at 100 °C under O2 in the presence of catalytic amounts of CeCl3–NaI gave an imine intermediate, which cyclised and dehydrogenated to give 2-arylbenzimidazoles or 2-arylbenzothiazoles in good yields.
