Compounds (η5-C5H4CH2CH2OCH3)TiCl3, (η5-C5H4CH2CH2OCH3)2TiCl2and (η5-C5H4CH2CH2OCH3)(η5-C5H5)TiCl2react with BBr3to give a high yield of titanium compounds containing cyclopentadienyl ligands with bromoethyl substituents, (η5-C5H4CH2CH2Br)TiBr3(1), (η5-C5H4CH2CH2Br)2TiBr2(3) and (η5-C5H4CH2CH2Br)(η5-C5H5)TiBr2(4), respectively. Hydrolysis of 1 in the presence of tert-butylamine affords cyclo-[(η5-C5H4CH2CH2Br)TiBr(μ-O)]4(2) in quantitative yield. The molecular structure of 2 was determined by X-ray diffraction.
