リサイクル型フルオラスGrubbs-Hoveyda 触媒の合成とそのメタセシス反応　

抄録

Organic molecules bearing small fluorous tags (C6F13,C8F17) are called light fluorous molecules. Light fluorous reagents, scavengers and catalysts are especially convenient since they typically induce reactions of organic substrates under the same conditions as their non-fluorous relatives, but are reliably removed from crude reaction products by fluorous solid phase extraction. Herein we report light fluorous versions of the first- and second-generation Grubbs-Hoveyda metathesis catalysts. These exhibit the expected reactivity profile, are readily recovered from reaction mixtures by fluorous solid phase extraction, and can be routinely reused five or more times. The catalysts can be used in a standalone fashion, or supported on fluorous silica gel.
