Several C2-symmetric bis(phospholyl) adducts of group 4 metals, including the first example of an η5-phospholyl complex of hafnium, have been synthesized and structurally characterized. These complexes undergo rac/meso isomerization in a process that is accelerated by Lewis bases. A C2-symmetric bis(phospholyl)zirconium dichloride binds as a bidentate ligand to Mo(CO)4. In the presence of methylalumoxane, bis(phospholyl)zirconium complexes serve as active catalysts for ethylene-hexene copolymerization reactions.
