| 摘 要： | <正> 近年来,高分子金属催化剂由于其特殊的高分子效应引起人们广泛关注,目前在国外市场上已有高分子金属催化剂商品供应,它较低分子有机金属催化剂活性更高,选择性更好,并已广泛用于加氢,硅氢加成,转化,醛化,分解,齐聚,聚合和不对称合成等很多反应中,然而对其结构的研究至今报道甚少。

| Abstract: | The structure of polymethylphenylsilaza-siloxane-Pd complex catalyst has been investigated by X-ray photoelectron spectroscopy (XPS). The experimental results indicated that the complex is formed by coordination of two lone pairs of electrons on two nitrogen atoms in polymethylphenylsilaza-siloxane to one palladium atom in palladium dichloride. The inactivation of the complex in the hydrogenation of olefines is due to the destroy of the complex and the reduction of Pd(Ⅱ) to Pd(0). |
