In 2022,Neerathilingam, Nalladhambi; Anandhan, Ramasamy published an article in RSC Advances. The title of the article was 《Metal-free photoredox-catalyzed direct α-oxygenation of N,N-dibenzylanilines to imides under visible light》.HPLC of Formula: 622-95-7 The author mentioned the following in the article:
An efficient synthesis of imides using metal-free photoredox-catalyzed direct α-oxygenation of N,N’-disubstituted anilines in the presence of 9-mesityl-10-methylacridinium [Acr+-Mes]BF4 as a photoredox catalyst and mol. oxygen as a green oxidant under visible light was developed. This photochem. approach offered operational simplicity, high atom economy with a low E-factor and functional group tolerance under mild reaction conditions. Control and quenching experiments confirmed the occurrence of a radical pathway and superoxide radical anion α-oxygenation reactions and also provided strong evidence for the reductive quenching of [Acr+-Mes]BF4 based on a Stern-Volmer plot, which led to the proposed mechanism of this reaction. The experimental process involved the reaction of 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7HPLC of Formula: 622-95-7)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) may be used to synthesize 1-(4-chlorobenzyl)-2-(pyrrolidin-1-yl-methyl)-1H-benzimidazole dihydrochloride.HPLC of Formula: 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
