Stereoselective Coordination of C5-Symmetric Corannulene Derivatives with an Enantiomerically Pure [Rh~I(nbd*)] Metal Complex

摘要

Numerous stereoselective catalytic processes rely on the differentiation of internally enantiotopic faces of planar π-systems by metal complexation. Chiral bowl-shaped molecules like 1,3,5,7,9-pentasubstituted corannulene, which invert rapidly on the reaction timescale, present themselves as achiral due to tautomeric equilibration of enantiomers, and thereby display externally enantiotopic it-faces.
