study dealing with the effect of phosphane fine‐tuning in ruthenium–indenylidene catalysts was performed. Challenged to establish how the electronic properties of para‐substituted phosphane ligands translate into catalyst activity, the versatile behaviour of these new ruthenium–indenylidenecomplexes was investigated for a number of metathesis reactions.

trifluoromethylamido-containing “boomerang” precatalysts bearing various N-heterocycliccarbene (NHC) ligands are reported. Comparative kinetic and stability studies show the significant effect of the NHC on the catalyst reaction profile. An investigation of the reaction scope for diverse metathesis transformations has allowed us to establish the influence of the NHC on catalyst activity, especially as a
