A simple and efficient method is demonstrated for the synthesis of benzimidazoles via cyclocondensation of o-phenylenediamine with aldehydes in the presence of catalytic amount of tert-butyl nitrite. All the reactions were carried out at room temperature while the desired products were obtained in good to excellent yields.

A green and efficient strategy for the synthesis of benzoxazoles, benzothiazoles and benzimidazoles has been developed by using inexpensive, readily available, dioxygen-stable and recyclable CuFe2O4as the nanocatalyst.
are still necessary. In this context, we report the concise synthesis of two polymeric frameworks (BTP-CMP and TBTP-CMP) incorporated into bithiophene and thiophthene units via a “bottom-up” strategy. BTP-CMP and TBTP-CMP were employed as heterogeneous photocatalysts in the synthesis of benzimidazoles, and exhibited excellentcatalyticactivity (up to 98% yield, at least 15 iterative runs). Therefore
