We provide an experimental summary of selected advances in olefin metathesis methodology that were reported over the past decades. A stable and universal sulfoxide‐chelated ruthenium olefin metathesis catalyst [RuCl2(SIMes)(=CH−C6H4−S(O)Ph)], SIMes=1,3‐bis(2,4,6‐trimethylphenyl)‐4,5‐dihydroimidazol‐2‐ylidene, was introduced and its application profile was studied in detail. A range of model substrates
我们提供了在过去几十年中报道的烯烃复分解方法的部分进展的实验总结。稳定且通用的亚砜螯合钌烯烃复分解催化剂[RuCl 2(SIMes)(= CH-C 6 H 4-S(O)Ph)],介绍了SIMes = 1,3-双(2,4,6-三甲基苯基)-4,5-二氢咪唑-2-亚基,并详细研究了其应用概况。已开发出一系列天然来源的模型底物,并成功地通过反应的变体进行了复分解,例如烯-炔,交叉或闭环复分解。报告的所有反应均在未经预处理的溶剂和空气中进行,以证明系统的用户友好性。除了已报道的配合物表现出的强大的官能团耐受性外,还确定了其与多种溶剂的相容性以及其空气和湿气的稳定性。另外,如果在约溶剂沸点的温度下进行反应,则观察到提高反应效率的有趣效果。
