• The one-pot photocatalytic synthesis of benzo[ f ]chromene was performed at room temperature by the addition of benzyl alcohol, malononitrile and β-naphthol in contact with an illuminated nano-SnO 2 /TiO 2 composite. This study illustrated the potential of photochemical synthesis of benzo[ f ]chromene. A simple procedure was proposed for the synthesis of a nano-SnO 2 /TiO 2 composite using the sol-gel method by hydrolysis of tin( iv ) chloride and titanium( iv ) chloride at room temperature in the presence of polyethylene glycol 200, diethanolamine, and distilled water. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and FT-IR were employed to characterize the proposed photocatalyst. Synthesis of chromene using an illuminated nano-SnO 2 /TiO 2 composite through a three component reaction which enables the generation of molecular complexity and diversity with good product yields (up to 80%).
