摘要：

Vinylidene complexes [Ru{NCNC(H)(CRRCH2C)-R-1-C-2(Me)=CH2}(eta(5)-C9H7)(PPh3)(2)][BF4] undergo an intramolecular coupling between the alkenyl-vinylidene fragment and the eta(5)-indenyl ligand to afford indene-metallacyclic compounds (6a,b) in which the resulting functionalised indene group is eta(6)-coordinated to the metal.
