The synthesis of four new bis(oxazoline) (BOX) derivatives bearing two additional coordination sites at the 4,4′-positions is presented. As these BOX scaffolds contain an unsubstituted methylenebridge, they should be capable of forming neutral metal complexes. Thus, these molecules are very interesting ligands for bifunctional catalysis. In addition, one BOX scaffold bearing two azide moieties was
