title: Photochemical preparation of pyrimidin-2(1H)-ones by rhenium(I) complexes with visible light.
abstract: With visible light irradiation (λ > 400 nm) of rhenium(I) complexes (P1-P4), a photochemical conversion from 3,4-dihydropyrimidin-2(1H)-ones to pyrimidin-2(1H)-ones at room temperature has been achieved with good to excellent yields in CH(3)CN-H(2)O solution containing CCl(4) and K(2)CO(3). Luminescence quenching study and product analysis reveal that photoinduced electron transfer between rhenium(I) complex P and 3,4-dihydropyrimidin-2(1H)-ones plays an important role in the initial event.
