چکیده:

BTSA.Nano-SiO2 efficiently catalyzes the condensation of benzene-1,2-diamine with aromatic aldehydes in the presence of atmospheric air as a green oxidant in ethyl acetate at room temperature toafford benzimidazole derivatives in high yields and in short reaction times. The reaction is also efficiently performed using BTSA.Nano-SiO2 whencarboxylic acids are used instead of aldehydes.
