Syntheses and Characterization of the First Cycloheptatrienyl Transition-Metal Complexes with a M-CF<sub>3</sub> Bond

The organometallic chemistry of metal complexes with organocyclic ligands of higher than five hapticity is much more lacking than the chemistry of metal complexes with η<sup>5</sup>-cyclopentadienyl ligands, which has been explored in considerable depth, resulting in novel advances. The...
