Brintzinger, Hans-Herbert Smith, James A. 2013-07-31T07:01:13Z Brintzinger, Hans-Herbert Ansa-metallocene derivatives : III. Influence of an interannular ethylene bridge on the reactivity of titanocene derivatives Titanocene derivatives with an interannular ethylene bridge, while resembling their unbridged counterparts in many transformations involving Ti<sup>IV</sup> or Ti<sup>llI</sup> oxidation stages, do not follow reaction paths previously observed for unbridged titanocene in a number of reactions, such as formation of a Ti<sup>II</sup> dinitrogen complex, isotope exchange of the cyclopentadienyl riIig ligands with D<sub>2</sub>, or formation of a Ti<sup>III</sup> hydride compound. These reactions are considered to be blocked by the unavailability of a «free" titanocene species, [(CH<sub>2</sub>) sub>2</sub>-(C<sub>5</sub>H<sub>4</sub>)<sub>2</sub>Ti<sup>II</sup>]<sub>n</sub>, as an intermediate in such systems. 2013-07-31T07:01:13Z Smith, James A. 1981 Journal of Organometallic Chemistry ; 218 (1981), 2. - S. 159-167 deposit-license eng
