Neutral and cationic half-sandwich complexes of ruthenium, rhodium and iridium with chiral [(S)-1-[(R)-2-(diphenylphosphino)ferrocenyl]ethyl]di-t-butylphosphine selenide (L, 1) were prepared and characterized. Monoselenation of the com. available chiral bisphosphine afforded potentially bidentate, first enantiomerically pure chiral bisphosphine monoselenide ligand 1, which was reacted with metal half-sandwich dichlorides to give monodentate neutral complexes [Cp*M(L-κP)Cl2] (Cp* = η5-C5Me5; 2, 3; M = Rh, Ir) and [(η6-p-cymene)Ru(L-κP)Cl2] (4). Reaction of 2-4 with NaSbF6 gave cationic complexes [Cp*M(L-κP,κS)Cl]SbF6 (5, 6) and [(η6-cymene)Ru(L-κP,κS)Cl]SbF6 (7), resp., in which the ligand L is bound in a bidentate P,S-mode. The complexes 2-7 were characterized spectroscopically and, for complexes 3, 7 and [Cp*Ir(L-κP,κS)Cl]ClO4 (6′) the crystal structures are reported. The chirality of the ligand influences and controls the metal-centered chirality yielding one of two possible chelate complexes with high diastereoselectivity.
