摘要：

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.
