چکیده
|
In this paper, we report an efficient and easy method for preparing 2-arylbenzimidazoles from ophenylenediamines and aldehydes under microwave irradiation and using a small amount of a new surfactant-modified moroccan clay catalyst. the heterogeneous reaction conditions provided a very simple, environmentally-friendly, clean, economical and selective protocol for the preparation of benzimidazole derivatives. the catalyst is easily recycled, and can be reused without loss of catalytic activity.
