Abstract
Olefin metathesis is a powerful tool for the formation of carbon−
carbon double bonds. Several families of well-defined ruthenium (Ru) catalysts
have been developed during the past 20 years; however, the reaction mechanism
for all such complexes was assumed to be the same. In the present study, the
initiation mechanism of Ru−indenylidene complexes was examined and
compared with that of benzylidene counterparts. It was discovered that not all
indenylidene complexes followed the same mechanism, highlighting the
importance of steric and electronic properties of so-called spectator ligands,
and that there is no single mechanism for the Ru-based olefin metathesis reaction.
The experimental findings are supported quantitatively by DFT calculations.
