Titanocene fixation-reduction mechanism

Figure 5. Evaluation of proposed titanocene fixation-reduction mechanism...

Titanocene chemistry provides an appropriate basis for a discussion of mechanism. Figure 4 shows a recent interpretation of the titanocene fixation-reduction process (13) submitted for publication by the Olives three or four months after our titanocene-N2 paper appeared (II). The mechanism is a complicated one, based essentially on ESR results meas-... 

Secondly, in the Olive mechanism, the fixing species is formed by a three-electron change starting with titanocene dimer. We subjected ti-tanocene to a three-electron naphthalenide reduction and have not been able to observe any nitrogen fixation of any kind with the resulting species.
