Abstract
The reaction of the doubly bridged bis(1,1′,2,2′-dimethylsilanodiyl)-η5-dicyclopentadienyl titanium and zirconium complexes Full-size image (<1 K) with water gave the μ-oxo derivatives Full-size image (<1 K). Addition of one equivalent of M′R (M′ = MgCl, R = CH3, CH2SiMe3; M′ = Li, R = CH2CME2Ph) to toluene or diethyl ether solutions of Full-size image (<1 K) afforded the chloro alkyl derivatives [M{(SiMe2)2(η5-C5H3)2}CIR]Full-size image (<1 K). Compounds 3 and 4 reacted with [CPh3][B(C6F5)4] at −78°C in CD2Cl2 leading to the cationic species Full-size image (<1 K) as demonstrated by NMR spectroscopy. The titanium(III) and zirconium(III) serivatives [M{(SiMe2)2(η5-C5H3)2} (μ-Cl)2 (M = Ti (12), Zr (13)) were obtained by reduction of 1 amd 2 with one equivalent of sodium amalgam. The X-ray molecular structure of [Ti{(SiMe2)2(η5-C5H3)2}Me2] (3) has been determined by diffraction methods.
