Salan ligands assembled around chiral bipyrrolidine: predetermination of chirality around octahedral Ti and Zr centres.
The first synthesis of Salan ligands assembled around the chiral 2,2'-bipyrrolidine backbone is described; as chelation to a metal can only occur via specific faces of the two pyrrolidine nitrogens, these ligands lead to predetermined chirality at metal centres of octahedral titanium and zirconium complexes.
