cross-metathesis reactions in water, involving water-insoluble substrates, at room temperature and using commercially available catalysts are reported. The key to success is to include small percentages of the nonionic, vitamin E-based amphiphile "PTS". The nanometer micelles formed accommodate water-insoluble substrates, along with a readily available Ru-based metathesis catalyst. Reactions proceed
报道了在室温下并使用可商购的催化剂在水中的不对称烯烃交叉复分解反应的第一个实例,涉及不溶于水的底物。成功的关键是包含少量非离子的,基于维生素E的两亲物“ PTS”。形成的纳米胶束可容纳水不溶性底物,以及易于获得的Ru基复分解催化剂。反应在环境温度下高效且极高的E选择性进行,产物易于分离。
