Grubbs-Hoveyda Second-Generation Catalysts Activated by the Introduction of a Light Fluorous Tag onto the Bidentate Ligands

Various novel Grubbs-Hoveyda second-generation catalysts activated by a fluorous tag on the ligands were prepared. The catalyst bearing the 1-naphthyl group on the bidentate ligand exhibited the highest catalytic activity among the studied catalysts for the ringclosing- metathesis reaction of diethyl 2-allyl-2-( 2-methylallyl) malonate.
