Abstract

Vinylidene complexes [Ru{ [double bond, length as m-dash] CC(H)CR¹R²CH₂C(Me)CH₂}(η⁵-C₉H₇)(PPh₃)₂][BF₄] undergo an intramolecular coupling between the alkenyl-vinylidene fragment and the η⁵-indenyl ligand to afford indene-metallacyclic compounds (6a,b) in which the resulting functionalised indene group is η⁶-coordinated to the metal.
