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 CH3CN−H2O solution containing CCl4 and K2CO3. Luminescence quenching study and product analysis reveal that photoinduced electron transfer between rhenium(I) complex P and 3,4-dihydropyrimidin-2(1H)-ones
与铼的可见光照射(λ> 400nm)的(I)配合物(P1 - P4)由3,4-二氢嘧啶2,光化学转化(1 ħ) -酮向嘧啶-2-(1 ħ) -酮在在含有CCl 4和K 2 CO 3的CH 3 CN-H 2 O溶液中,室温可以达到良好或极好的收率。发光猝灭研究和产物分析表明rh(I)配合物P和3,4-dihydropyrimidin-2(1 H)-ones之间的光诱导电子转移在初始事件中起重要作用。
