How important is the release-return mechanism in olefin metathesis?
From whose bourns no traveller returns, puzzles the will: UV/Vis, 19F NMR, and fluorescence spectroscopic studies (see graphic) provide no evidence supporting the boomerang mechanism in Grubbs-Hoveyda complexes, which is the return of the isopropoxy styrene as a benzylidene ether ligand following its release during catalyst initiation.

Activated pyridinium-tagged ruthenium complexes as efficient catalysts for ring-closing metathesis
New pyridinium-tagged ruthenium catalysts have been synthesised to perform olefin metathesis in several media including both organic and aqueous solvents and room temperature ionic liquids (RTILs). High activity was obtained in the ring-closing metathesis (RCM) of a variety of di- or tri-substituted and/or oxygen-containing dienes. However, only fair levels of recycling combined with low to moderate residual ruthenium levels (25-173 ppm) have been observed showing clearly the difficulty of associating high activity and recyclability.
