The aim of the present study is to develop readily available and stable pre‐catalysts that could be easily prepared on large scale from simple starting materials. Based on the hypothesis that substitution of classical PCy 3 with phosphanes of varying electron‐donating properties could be a straightforward manner to improve catalytic activity, a methodical 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–indenylidene complexes was investigated for a number of metathesis reactions.
