Reactivity of [Cp2Ti(CO)2] towards Nitrile and Water Adducts of B(C6F5)3: Formation of [Cp2Ti(η2‐F3CC6H4CN)·B(C6F5)3] and [Cp2Ti][HOB(C6F5)3] with a Ti···F Interaction

The reaction of [Cp2Ti(CO)2] with borane adducts CF3C6H4CN·B(C6F5)3 and [H2O·B(C6F5)3] has afforded the titanaazirine [Cp2Ti(η2‐C,N‐F3CC6H4CN)·B(C6F5)3] (1) and the TiIII salt [Cp2Ti][HOB(C6F5)3] (2), respectively. In both cases, a Ti···F interaction between the titanium centre and an ortho‐fluorine atom of the tris(perfluorophenyl)borane is observed in the X‐ray structure determination.
