REDOX REACTION OF ARENETITANIUM(II) COMPLEXES WITH CYCLOPENTADIENE LEADING TO (ETA-5-CYCLOPENTADIENYL)TITANIUM(III) COMPLEXES - EPR STUDY

Bis(dichloroalanedi-μ-chloro)(η6-arene)titanium(II) complexes are readily oxidised by cyclopentadiene to yield (η5-clopentadienyl)bis(dichloroalanedi-μ-chloro)titanium(III). Upon further addition of cyclopentadiene the AlCl4 ligand is replaced by cyclopentadienyl to give (di-η5-cyclopentadienyl)(dichloroalanedi-μ-chloro)titanium(III). Similar reactions were observed with bis(dibromoalanedi-μ-bromo)(gh6-benzene)titanium(II). The structures of both the initial and final complexes are confirmed by this redox reaction. © 1979.
