One-pot photocatalytic synthesis of quinaldines from nitroarenes with Au loaded TiO2 nanoparticles

► Nano-Au-TiO2 photocatalyses a combined redox reaction with nitroarene and ethanol. ► Quinaldines have widespread biochemical significance due to their application. ► Our reaction conditions provide selective one-pot synthesis of quinaldine. ► Synthesis of quinaldines from nitroarenes are rare in the literature. ► Easy product isolation and mild conditions make this reaction eco-friendly.
