Abstract

Intramolecular cyclization of α,α-alkyl-ortho-methoxybenzylcyclopentadienyl titanium complexes to form titanoxacycle complexes promoted by BBr3has been studied. A probable two-step mechanism involving halogen exchange and intramolecular elimination was proposed. Four related benzyl-substituted cyclopentadienyl titanium complexes have been studied by X-ray crystallography.
