[reaction--see text] Ionic liquid 1-butyl-3-methylimidazoliumhexafluorophosphate ([bmim]PF(6)) is described as an effective medium for ring-closing metathesis (RCM) using Grubbs catalysts. When [bmim]PF(6) was used as solvent, the RCM showed high conversions and a broad substrate tolerance. [bmim]PF(6) and the ruthenium catalyst were recycled after extraction of the product in the organic phase for at least three cycles.
[反应——见正文] 离子液体1-丁基-3-甲基咪唑六氟磷酸盐([bmim]PF₆)被描述为使用格拉布催化剂进行闭环复分解反应(RCM)的有效介质。当[bmim]PF₆用作溶剂时,RCM显示出高转化率和广泛的底物耐受性。在将产物萃取到有机相后,[bmim]PF₆和钌催化剂至少循环使用了三个周期。
