Trinuclear Ru cluster photocatalysts that contain two Ru(II) photosensitizers and a Ru(II) reaction center are prepared, and their activity in the photocatalytic oxygenation of a sufide and alkenes is investigated. Photoirradiation (visible light) and the use of a Co salt ([Co(NH3)5Cl]Cl2, as an electron acceptor) are found to be essential for these catalytic reactions. The O atom of the water solvent
制备了包含两种Ru(II)光敏剂和Ru(II)反应中心的三核Ru簇光催化剂,并研究了它们在硫化物和烯烃的光催化氧化中的活性。对于这些催化反应,发现光辐照(可见光)和使用Co盐([Co(NH 3)5 Cl] Cl 2作为电子受体)是必不可少的。通过逐步电子转移和水配体在反应中心的去质子化,将水溶剂的O原子(pH 6.8)转移到基质上。通过这些过程,在反应中心配位的水配体被转化为Ru V = O物种,它是硫化物和烯烃氧合的活性中间体。
