Selective and eco-friendly procedures for the synthesis of benzimidazole derivatives. The role of the Er(OTf)(3) catalyst in the reaction selectivity
An improved and greener protocol for the synthesis of benzimidazole derivatives, starting from o-phenylenediamine, with different aldehydes is reported. Double-condensation products were selectively obtained when Er(OTf)(3) was used as the catalyst in the presence of electron-rich aldehydes. Convers...
