Unexpected coupling between an η5-indenyl ligand and alkenyl-vinylidene fragments: synthesis of unprecedented (η6-indene)ruthenium(ii) metallacycles†
Abstract
Vinylidene complexes [Ru{CC(H)CR1R2CH2C(Me)CH2}(η5-C9H7)(PPh3)2][BF4] undergo an intramolecular coupling between the alkenyl-vinylidene fragment and the η5-indenyl
