- Copper‐modified titanium dioxide nanoparticles as a highly efficient photocatalyst for the synthesis of furan‐3‐carboxylate derivatives Muhammad Saleh Faryabi Ali Akbari Mahboobeh Zahedifar Photochemistry and Photobiology Abstract A heterogeneous photocatalyst based on copper‐modified titanium dioxide nanoparticles has been prepared and characterized. Copper‐modified nano‐titanium dioxide (Nano‐TiO 2 @CuO) is an efficient photocatalyst for the synthesis of furan‐3‐carboxylate derivatives through a radical addition–polar cyclization of β ‐ketoester derivatives and allyl chloride under the irradiation of blue light. Copper‐modified titanium dioxide nanoparticles 20% which show titanium dioxide‐copper cooperativity show a significantly better performance with respect to turnover numbers (number of product molecules per catalyst molecule = efficiency). The Nano‐TiO 2 @CuO catalyst is stable and can be reused multiple times without a significant change in activity. The particle sizes varied in the range of 25–80 nm. High yields of product, environmentally friendly, cost‐effective method, and easy work‐up are advantages of the present method. All synthesized compounds were characterized by NMR and FT‐IR spectroscopy. 10.1111/php.14111 http://onlinelibrary.wiley.com/termsAndConditions#vor
