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