Synthesis of Pyrido[1,2-a]benzimidazoles by Electroreductive Heterocyclization of 1-(2-nitroaryl)pyridinium Chlorides was written by Sokolov, Aleksandr A.;Syroeshkin, Mikhail A.;Begunov, Roman S.;Rusakova, Nadezhda N.;Gultyai, Vadim P.. And the article was included in Mendeleev Communications in 2012.Application In Synthesis of Ethyl 4-chloro-3-nitrobenzoate This article mentions the following:
The electrochem. reduction of N-(2-nitro-4-R-phenyl)pyridinium chlorides (R = CF3, CN, CO2Et) at a lead cathode in HCl/iPrOH/H2O affords the corresponding 7-R-pyrido[1,2-a]benzimidazoles in 70-94% yields. In the experiment, the researchers used many compounds, for example, Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2Application In Synthesis of Ethyl 4-chloro-3-nitrobenzoate).
Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Application In Synthesis of Ethyl 4-chloro-3-nitrobenzoate
