Abstract

Unprecedented zirconium(II) complexes bearing tethered olefin - phosphine ligands were synthesized and characterized. The molecular structures of the newly synthesized complexes (η⁵-1,2-Me₂C₅H₃) ₂Zr(CH₂=CHCH₂CH₂PPh₂) (1c) and Cp₂Zr(CH₂=CHCH₂CH₂CH ₂PPh₂) (2a) were determined by single-crystal X-ray diffraction methods. The stability and reactivity of the series of complexes Cp₂Zr{CH₂=CH(CH₂)_nPR₂} (n = 2, 3; R = Et, Ph) were examined. The complex 2a showed simultaneously both sufficient stability and high reactivity.
