Coordination chemistry of half-open trozircenes: Adduct formation of [(η7-C7H7)Zr(η5-2,4-C7H11)] with isocyanides, phosphines and N-heterocyclic carbenes

The reactivity of the half-open trozircene [(η7-C7H7)Zr(η5-2,4-C7H11)] towards the two-electron donor ligands tert-butyl isocyanide (CN-tBu), 1,2-bis(dimethylphosphino)ethane (dmpe), trimethylphosphine (PMe3) and 1,3,4,5-tetramethylimidazolin-2-ylidene (IMe) has been investigated. The resulting 1:1 adducts are discussed based on experimental and theoretical results.
