摘　　要：A metal-free and environmentally friendly aerobic aromatization photosensitized by organic dye eosin Y bis(tetrabutyl ammonium salt)(TBA-eosinY)has been developed.With the aid of K_(2)CO_(3),the aerobic catalytic system converts 1,4-dihydropyridines to their corresponding pyridine derivatives efficiently under visible light irradiation(λ=450 nm)at room temperature.
