摘要：
Intramolecular cyclization of alpha,alpha-alkyl-ortizo-methoxybenzylcyclopentadienyl titanium complexes to form titanoxacycle complexes promoted by BBr3 has 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. (C) 2002 Published by Elsevier Science B.V.
