With visible-light irradiation of the platinum(II) terpyridyl complex 1 (λ > 450 nm), an effective photocatalytic conversion from readily available 3,4-diaryl-2,5-dihydropyrroles (2a2e) to 3,4-diarylpyrroles (3a3e) and hydrogen (H2) is achieved with high efficiency and large catalytic turnover in a homogeneous solution.
