Sunlight‐Assisted Photocatalytic Sustainable Synthesis of 1,4‐Disubstituted 1,2,3‐Triazoles and Benzimidazoles Using TiO 2 −Cu 2 (OH)PO 4 Under Solvent‐Free Condition

Herein, we report the facile synthesis of 1,4‐disubstituted 1,2,3‐triazoles and benzimidazoles using TiO 2 −Cu 2 (OH)PO 4 as an efficient sunlight active nanophotocatalyst under solvent‐free condition. The highlights of the proposed protocol are simple, scalable with a broad substrate scope, short reaction time, excellent regioselectivity and catalyst recyclability. The use of recyclable photocatalyst and solvent‐free condition makes the catalytic system resulted in sustainable and environmental‐friendly procedure.
