The cleavage of ΔΔ[Rh(th4,5ppy) 2 (μ‐Cl)] 2 [th4,5ppy is enantiomerically pure (8 R ,10 R )‐2‐(2′‐thienyl)‐4,5‐pinenopyridine (−) ] by 5 different diimines and 11 diamines yields monomeric cations Δ[Rh(th4,5ppy) 2 ( N ∩ N )] + . In all cases, the cleavage reaction preserves the original Δ configuration at the metal center. When N ∩ N is a chiral or a prochiral ligand, various degrees of stereoselectivity is observed, depending on where the stereogenic center is located in N ∩ N . The reported results open up a systematic method towards the synthesis of tris(bidentate)Rh III complexes with a completely predetermined stereochemistry.
