Titanium organotitanium alkoxides

A few organotitanium alkoxides have been structurally determined. In bis-benzyl titanium diethoxide a centrosymmetric dimer [(C6H5CH2)4Ti2(/r-OEt)2(OEt)2] is formed involving five-coordinated Ti in a distorted TBP configuration. In bis-methyl titanium tritox methoxide (tritox = tri-tert-butyl carbinolate, BU3CO) the methoxo... 

However, in a comprehensive study, Seebach and coworkers have shown the usefulness of titanium and zirconium alkyls as selective nucleophilic reagents.106,107 Typically compounds of the type (RO)3MR (M = Ti, Zr) are reacted with aldehydes or ketones to yield asymmetric alkoxides (equation 32),107 The method has been extended to allow enantioselective addition using chiral organotitanium reagents where the chirality is imposed by the initial alkoxide substituents.107,108... 

Organotitanium compounds are usually liable besides cyclopentadienyltitanium compounds. Therefore, titanium organic compounds are not organotitanium compounds having a Ti—C bond but titanium alkoxide having a Ti—O bond [11,35].
