## Abstract Enantiomerically pure, vicinal diols 1 afforded in a two‐step synthesis (etherification and subsequent Claisen condensation) chiral bis‐1,3‐diketones H~2~L^(__S__,__S__)^ (3 a–c) with different substitution patterns. Reaction of these __C__~2~‐symmetric ligands with various transition‐m
