Substituent effects in reduction-induced synthesis of ansa-titanocenes
Original language description
Bis{(diphenylvinylsilyl)tetramethylcyclopentadienyl}/ntitanium dichloride [TiCl2{g5-C5Me4(SiPh2CH=/nCH2)}2] (1) is reduced with a half molar equivalent of/nmagnesium to the monochloride ([TiCl{g5-C5Me4(SiPh2-/nCH=CH2)}2] (2), whereas one molar equivalent of magnesium/naffords the titanocene [Ti{g5-C5Me4(SiPh2CH=/nCH2)}{g5:g2-C5Me4(SiPh2CH=CH2)}] (3) stabilized by/ng2-coordination of one of the two vinyl groups to titanium(/nII). In the presence of excess magnesium, the vinyl/nmoieties of 3 undergo intramolecular coupling to afford the/nansa-titanocene [Ti(g5:g5:g2-C5Me4SiPh2CH=CHCH2CH2-/nSiPh2C5Me4)] (4) possessing the g2-coordinated double/nbond in lateral position of its ansa-chain. The symmetrical/nansa-titanocene [Ti(g5:g5:g2-C5Me4SiPh2CH2CH=CHCH2-/nSiPh2C5Me4)] (5) was not obtained although its DFT-calculated/nenergy is only slightly higher than that of 4. It is/nconsidered that transient 5 gives rise to non-identified tarlike/nby-products which inherently accompany the formation/nof 4.
