Peng, Jinsong published the artcileCopper-catalyzed intramolecular C-N bond formation: a straightforward synthesis of benzimidazole derivatives in water, Product Details of C19H14N2, the publication is Journal of Organic Chemistry (2011), 76(2), 716-719, database is CAplus and MEDLINE.
A straightforward, efficient, and more sustainable copper-catalyzed method has been developed for intramol. N-arylation providing the benzimidazole ring system. With Cu2O (5 mol %) as the catalyst, DMEDA (10 mol %) as the ligand, and K2CO3 as the base, this protocol was applied to synthesize a small library of benzimidazoles, e.g., I in high yields. Remarkably, the reaction was exclusively carried out in water, rendering the methodol. highly valuable from both environmental and economical points of view.
