Unexpected coupling between an eta5-indenyl ligand and alkenyl-vinylidene fragments: synthesis of unprecedented (eta6-indene)ruthenium(II) metallacycles.
Copyright policy )Unexpected coupling between an eta5-indenyl ligand and alkenyl-vinylidene fragments: synthesis of unprecedented (eta6-indene)ruthenium(II) metallacycles.
Vinylidene complexes [Ru{=C=C(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.
