摘　　要：采用两相法简便合成了五种新的大位阻取代苯甲酸二茂钛配合物，经元素分析、ＩＲ和＾１ＨＮＭＲ对其组成及结构进行了表征，结果表明：羟基以单齿单氧形式与钛配位，可以得到二茂钛双分子取代配合物；而羟基邻位有酚羟基存在时，则配体以双齿形式与钛配位形成二茂钛六元环状化合物。An interfacial method to synthesis the complexes of titanocene with large steric substituted benzoic acid is reported. The complexes were characterized by elemental analisis, IR and 1H NMR spectra. Spectroscopic data suggest that only one oxygen of carboxyl in substituted benzoic acid is bound to Ti to form titanocene of bimolecular substituted complex. And if there is a hydroxyl in ortho position of carboxyl, the oxygen of hydroxyl and carboxyl in ligand are bound to Ti to form hexatomic cyclic compound.
