Hybrid crystal NH<sub>3</sub>(CH<sub>2</sub>)<sub>4</sub>NH<sub>3</sub>SiF<sub>6</sub> as an efficient catalyst for the synthesis of benzoxazoles, benzimidazoles and benzothiazoles under solvent-free conditions
<p>An easy synthetic protocol for the synthesis of biologically active benzimidazole, benzothiazole and benzoxazole derivatives has been demonstrated using a hybrid crystal NH<sub>3</sub>(CH<sub>2</sub>)<sub>4</sub>NH<sub>3</sub>SiF<sub>6</sub> as a mild and efficient heterogeneous catalyst. Short reaction times, solvent-free conditions, good to excellent yields, easy reusability and use of an eco-friendly catalyst are some of the significant attributes of the present method.</p
