An efficient and rapid one-pot method for the green synthesis of benzimidazole derivatives and catalysed by PVA@Cu(II) Schiff base complex is described. The catalyst demonstrates excellent performance, reusability and stability which can efficiently catalyst benzimidaoles in water medium. A number of benzimidazoles were prepared in up to high yields. The catalyst was recovered by simple filtration and reused for seven runs without any remarkable reactivity loss.
