Abstract

The behavior of new enantiopure imidazolinium salts bearing two hydroxy‐containing substituents as chiral shift reagents and as carbene precursors for diethylzinc addition to aldehydes is presented. The new hydroxy‐containing imidazolinium salts can be prepared in a few steps from amino alcohols and qualify as new tridentate ligands and ionic liquids.(© Wiley‐VCH Verlag GmbH & Co.
