Aza[6]helicene Platinum Complexes: Chirality Control of cis-trans Isomerism
Résumé
It was serendipitously observed that cis-[PtCl2(NCEt)PPh3] reacted differently with either racemic or enantiopure 4-aza[6]helicene, giving respectively cis (racemic) and trans (enantiopure) [(PtCl2)-Cl-II(4-aza[6]helicene)PPh3] complexes. This unexpected reactivity is explained through a dynamic process (crystallization-induced diastereoselective transformation) and enables a new aspect of reactivity in chiral transition-metal complexes to be addressed.
