## Abstract Silica phenyl sulfonic acid (SPSA) was prepared and effectively used in the oneβpot synthesis of 2βarylβ1βarylmethylβ1Hβ1,3βbenzimidazoles from __o__βphenylenediamine with aldehydes in water in the presence of tetrabutyl ammonium bromide with good to high yield. Also, SPSA was used as a
In this paper, a green and facile protocol was described which was efficient for synthesis of benzimidazoles using nanoβFe~3~O~4~ catalyst with continuous bubbling of air as the oxidant in PEGβ400/H~2~O aqueous system at room temperature. This protocol afforded the target products in good to excelle
