has been found to efficiently promote the cross‐metathesis between substituted alkenes and ethylene, while continuously migrating the double bond along the alkenyl chain (see scheme). When alkenylarenes, such as the natural products eugenol, safrol, or estragol, were treated with this catalyst under an ethylene atmosphere, they were cleanly converted into the corresponding styrenes and propylene gas
收缩链:由[Pd(μ-Br)(t Bu 3 P)} 2组成的双金属体系和钌复分解催化剂可有效促进取代烯烃与乙烯之间的交叉复分解,同时持续迁移沿烯基链的双键(请参见方案)。当在乙烯气氛下用该催化剂处理链烯基芳烃(例如天然产物丁子香酚,藏红花或雌二醇)时,将它们干净地转化为相应的苯乙烯和丙烯气体。
