A simple and green methodology has been developed for the syntheses of some new 2-styrylbenzimidazoles. In this method, 2-styrylbenzimidazoles 6(a–x) were synthesized by the condensation of o-phenylenediamines 4(a–c) with cinnamic acids 3(a–h) using glycerol containing boric acid (10 mol%) as the reaction medium at 180 °C about 3–5 h. The cinnamic acids(More)
