Abstract

The silyl-substituted titanocene complex, (η⁵-C₅Me₄SiMe₂Ph)₂Ti, coordinates dinitrogen upon cooling to -35 °C to yield an unprecedented example of a mono(dinitrogen) complex of a substituted bis(cyclopentadienyl) titanium compound, (η⁵-C₅Me₄SiMe₂Ph)₂Ti(N₂). Analogous monocarbonyl derivatives, (η⁵-C₅Me₄R)₂Ti(CO) (R = SiMe₃, SiMe₂Ph, CHMe₂), have been prepared by mixing the dicarbonyl compounds with the corresponding sandwiches. Both (η⁵-C₅Me₄SiMe₂Ph)₂Ti(N₂) and (η⁵-C₅Me₄SiMe₂Ph)₂Ti(CO) have been characterized by X-ray diffraction, and mixed N₂-CO titanocene complexes have also been observed by in situ IR spectroscopy.
