title: Flexible Structural Features of Pentafulvene Titanium Derivatives: Isolation and Characterization of NHC Complexes.
abstract: The reaction of η(5),η(1)-pentafulvene titanium complexes with the strong N-heterocyclic carbene (NHC) donor 1,3,4,5-tetramethylimidazole-2-ylidene, leads to the formation of isolable NHC titanium adducts, featuring a haptotropic shift of the pentafulvene ligand, proved by single crystal X-ray diffraction as well as NMR spectroscopy studies.
