| Abstract: | The diastereoselective κ2-P,N-coordination of a chiral tricyclic β-iminophosphine ligand to the half-sandwich ruthenium(II) fragments RuCl(η6-arene)]+ (arene = C6H6, p-cymene, 1,3,5-C6H3Me3, C6Me6), Ru(η6-p-cymene)(NCMe)]2+ and Ru(η5-C5H5)(NCMe)]+ is described. The structures of the resulting mono- and dicationic cymene derivatives have been confirmed by X-ray crystallography. Studies on the catalytic activity of these Ru(II) compounds in Diels–Alder cycloaddition processes are also reported. |
