Visible light catalyzed aromatization of 1,3,5-triaryl-2-pyrazolines by platinum(II) polypyridyl complex under oxidant-free condition

Articles SPECIAL TOPIC · Organic Photochemistry

Abstract

With visible light (λ=450 nm) irradiation of a catalytic amount of platinum(II) terpyridyl complex, 1,3,5-triaryl-2-pyrazolines can be smoothly converted to their corresponding pyrazoles and hydrogen in quantitative yields with no use of any oxidant at room temperature.
