建立了以[CpRu(CH3CN)(3)]PF6、2-喹啉甲酸和2-丙烯-1-醇为原料定量合成[CpRu(IV)(pi-C3H5)(2-quinolinecarboxylato)]PF6的简便有效的方法。阳离子Ru(IV)络合物对空气和水分都是稳定的，可以在小瓶中储存至少六个月。该络合物实现了烯丙基醚在甲醇中的脱烯丙基反应和醇的脱水烯丙化反应，操作简便。此外，通过从反应体系中去除挥发性的烯丙基甲醚副产物，该催化剂可以实现10000次烯丙基醚裂解的循环。
A facile and efficient method for the quantitative synthesis of [CpRu(IV)(pi-C3H5)(2-quinolinecarboxylato)]PF6 from [CpRu(CH3CN)(3)]PF6, 2quinolinecarboxylic acid, and 2-propen-1-ol has been established. The cationic Ru(IV) complex is air- and moisture-stable, and can be stored in a vial for at least six months. This complex realizes a simple and easy operation for both the deallylation of allyl ethers in methanol and the dehydrative allylation of alcohols. Furthermore, with removal of the volatile allyl methyl ether co-product from the reaction system, the robust catalyst can attain a turnover of 10000 cycles of allyl ether cleavage.
