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:羧基以单齿单氧形成与钛配位,可以得到二茂钛双分子取代配合物;而羧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 analysis, 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.
