PPh₃ Propeller Diastereomers: Bonding Motif Ph_PPh3 Face-On π-Ar in Half-Sandwich Compounds [(π-Ar)LL'MPPh₃].

ABSTRACT: Chiral-at-metal compounds (R _Ru,S _C)/(S _Ru,S _C)-[CyRu(1O-2N)PPh₃]PF₆ and (R _Ru,S _C)/(S _Ru,S _C)-[CyRu(2O-1N)PPh₃]PF₆ were prepared using anions 1O-2N^- and 2O-1N^- of the Schiff bases, derived from the hydroxynaphthaldehydes and (S)-1-phenylethylamine. The pure (R _Ru,S _C)-diastereomers were obtained by crystallization. In the unit cell of (R _Ru,S _C)-[CyRu(1O-2N)PPh₃]PF₆, there are three independent molecules, which differ in the propeller sense of the PPh₃ ligand. Molecules [1
