coordination of different metal ions at enantiotopic positions of an achiral meso‐ligand are reported. These catalysts exhibit a pseudo‐Cs symmetry and are able to catalyze reactions demanding simultaneous involvement of two catalytic sites. The latter was demonstrated by application in the asymmetric ring‐opening of meso‐epoxides.
