Description
| - Half sandwich pentamethylcyclopentadienyltitanium chloroisopropoxides [Ti(eta5-C5Me5)Ti(Oi-Pr)nCl3-n] (n = 1 (1) or 2 (2)) and methylisopropoxides [Ti(eta5-C5Me5)Ti(Oi-Pr)nMe3-n](n = 1(3) or 2(4)) were prepared and characterized by spectroscopic methods, and compound 1 by single crystal X-ray diffraction analysis. Compounds 3 and 4 were reacted with an equimolar quantity of B(C6F5)3, however, only compound 4 afforded a crystalline product of limited stability at ambient temperature. Its single crystal X-ray diffraction analysis revealed that it is the zwitterionic complex [(eta5-C5Me5)Ti(Oi-Pr)2]+[(mu-Me)B(C6F5)3]- (5) and its crystal structure is very similar to the recently reported tert-butoxy complex [(eta5-C5Me5)Ti(Ot-Bu)2]+[(mu-Me)B(C6F5)3]- (6). The 1H, 13C, and 19F NMR spectra in C6D6 solution also showed the features analogous to those of 6. 1D NOESY experiments proved a close through space interaction of irradiated C5Me5 or OCHMe2 protons with the bridging Ti... Me-B group.
