Novel routes to bidentate cyclopentadienyl-alkoxy complexes of titanium
No full textReaction of C5R14 (SiMe3)CHR2CH2CR3CR4OR5 with titanium tetrachloride gives bidentate (η5, σ-C5R14CHR2CH2CR3R4O) TiCl2 through elimination of ClSiMe3 and RCl (R = SiMe3, CH2Ph and CMe3). A potentially tridentate system (R1, R2, R3 = H, R4 = -(CH2)2OMe) was synthesised in optically pure form. X-ray structure determination, and NMR studies confirmed that the pendant ether did not co-ordinate to the metal and the complex gave no enantioinduction in hydride transfer reactions. Efficient routes to tetramethylcyclopentadienyl substituted ligands (R1 = Me) were developed through the addition of 2-magnesio-2-butene to γ-lactones followed by protection of the so formed pendant primary hydroxyl group and acid catalysed cyclisation. Indenyl and fluorenyl ligands carrying 3-hydroxypropyl substituents were synthesised, but did not form stable titanium complexes. The bidentate cyclopentadienyl-alkoxy titanium complexes were active catalysts for a variety of transformations.</p
