2-position of the pyridine system and/or palladium complexes with enantiomerically pure co-ligands. The tripod ligand 3b contains three different binding sites (Cp, P, N) connected by a resolved chiral carbon atom. (SC)-configuration of this tripod ligand enforces (RRh)-configuration at the metalatom in the halfsandwich rhodium complex (LMent,SC,RRh)-7b. The opposite metal configuration is inaccessible. Substitution
