The new ruthenium compound [Ru(NO)(pysiS4)]Br (3) (pysiS4 = 2,6-bis(3-triphenylsilyl-2-sulfanylphenylthiomethyl)pyridine), containing sterically bulky SiPh3 groups ortho to the thiolate donors, has been synthesized. In solution, 3 releases NO efficiently on exposure to visible light (lambda >/= 455 nm) at room temperature to afford [Ru(Br)(pysiS4)] (4). Treatment of 4 with NO yielded exclusively 3 without any metal-bound side reaction.
新型钌化合物[Ru(NO)(pysiS4)]Br (3)(pysiS4 = 2,6 - 双(3 - 三苯基硅基 - 2 - 硫代苯基硫甲基)吡啶)已被合成,该化合物在硫醇盐供体的邻位含有空间位阻较大的SiPh3基团。在溶液中,3在室温下暴露于可见光(λ≥455 nm)时能有效释放NO,生成[Ru(Br)(pysiS4)] (4)。用NO处理4时,只生成了3,没有发生任何金属结合的副反应。
