Synthesis of a family of monomeric, base-free bis(cyclopentadienyl)titanium oxide complexes, (eta(5)-C5Me4R)(2)TiO (R = Pr-i, SiMe3, SiMe2Ph), has been accomplished by deoxygenation of styrene oxide by the corresponding sandwich compound. One example, (eta(5)-C5Me4SiMe2Ph)(2)TiO, was characterized by X-ray diffraction. All three complexes undergo clean and facile hydrogenation at 23 degrees C, yielding the titanocene hydroxy hydride complexes (eta(5)-C5Me4R)(2)Ti(OH)H. For (eta(5)-C5Me4SiMe3)(2)TiO, the kinetics of hydrogenation were first-order in dihydrogen and exhibited a normal, primary kinetic isotope effect of 2.7(3) at 23 degrees C consistent with a 1,2-addition pathway. Isotope effects of the same direction but smaller magnitudes were determined for silane addition.
