Substituted benzimidazoles and pyrimidazoles are an important group of heterocyclic aromatic organic compounds in the field of medicinal chemistry. A one-step microwave accelerated synthesis of substituted benzo- and pyridine-fused 1H-imidazoles has been described. Mechanistically, the reaction proceeds by reacting substituted 2-fluoronitrobenzene and substituted arylamine through the formation of N-hydroxy intermediate, which at higher temperature cleaves to afford the desired product. This approach achieved reductions in reaction times, higher yields, cleaner reactions than the previously described synthetic processes.

Arnold, Eric P.,Mondal, Prolay K.,Schmitt, Daniel C.
supporting information, p. 1 - 5 (2020/02/20)
An efficient approach to the parallel synthesis of benzimidazoles from anilines is described. Library approaches to vary the N1 and C2 vectors of benzimidazoles are well established; however, C4-C7 variation has traditionally relied on 1,2-dianiline build

Photophysical characteristics of 2-(4′-amino-2′-hydroxyphenyl)-1H-imidazo-[4,5-c]pyridine (AHPIP-c) have been studied in various aprotic and protic solvents using UV-visible, steady state fluorescence and time-resolved fluorescence spectroscopic technique
Catalyst-free one-pot synthesis of benzimidazoles from 1,2-diaminoarenes and alcohols

supporting information, p. 6520 - 6525 (2015/01/08)
A new and efficient protocol is described for the one-pot synthesis of benzimidazoles from a variety of aryl alcohols and 1,2-diaminoarenes. The yields were ranging from moderate to excellent. Moreover, the present method is utilizing alcohols instead of aldehydes and the reactions are carried out under solvent- and catalyst-free conditions, offering an environmentally benign process.
Selective autoxidation of benzylamines: Application to the synthesis of some nitrogen heterocycles
Nguyen, Thanh Binh,Ermolenko, Ludmila,Al-Mourabit, Ali

A green and remarkably simple synthesis of nitrogen heterocycles from benzylamines and anilines o-substituted by a cyclizable group has been developed based on selective uncatalyzed autoxidation of benzylamines.
Na2S2O4: A versatile reagent for the one-pot synthesis of 2-aryl-1h-imidazo[4,5-c]pyridines from 4-amino-3- nitropyridine and aldehydes via reductive cyclization
Dubey,Chowdary,Ramesh,Reddy, P. V. V. Prasada
, p. 697 - 708 (2011/03/19)
A highly efficient and versatile method for the synthesis of 2-aryl-1H-imidazo[4,5-c]pyridines 3 was achieved in one step via reductive cyclization of 4-amino-3-nitro-pyridines 4 with aromatic aldehydes in the presence of Na2S2O
New one-pot procedure for the synthesis of 2-substituted benzimidazoles
Sharghi, Hashem,Asemani, Omid,Khalifeh, Reza
, p. 1128 - 1136 (2008/09/18)
A highly selective synthesis of 2-substituted benzimidazole derivatives from the reaction of o-phenylendiamine derivatives and aromatic aldehydes in the presence of an organic salt, NH4OAc, in absolute ethanol is presented. The products were obtained by evaporating the solvent followed by a simple recrystallization with excellent yields. Copyright Taylor & Francis Group, LLC.
