Synthesis and RCM Reactions Using a Recyclable Grubbs-Hoveyda Metathesis Catalyst Activated by a Light Fluorous Tag

A recyclable Grubbs-Hoveyda second-generation catalyst activated by a light fluorous tag was prepared The modified light fluorous catalyst exhibited higher catalytic activity than the parent or the previously reported light fluorous variant for RCM reactions and could be routinely recovered The light fluorous tag incorporated in the catalyst served as both an activator as well as a handle for separation and recovery with fluorous solid-phase extraction
