金属有机配合物一般在严格无水的有机相中合成,然而近年来在有水条件下合成二茂钛配合物(水相法和两相法)引起了广泛的兴趣。本文报道了二氯二茂钛乙酰丙酮的水溶液与(环取代)水杨酸钠水溶液的反应,探讨了影响该水相合成反应结果的几种因素,并同时提出了一种新的合成二茂钛水杨酸类配合物的两相法,合成了八个新的二茂钛(环取代)水杨酸配合物(Ⅱ—Ⅷ,Ⅹ),且首次由两相法合成了配合物Ⅰ。反应如下式所示:
Metal-organic complexes are generally synthesized in a strictly anhydrous organic phase. However, the synthesis of titanocene complexes (aqueous and two-phase methods) under water conditions has attracted widespread interest in recent years. In this paper, the reaction of dichloro titanocene acetylacetone aqueous solution with (ring substituted) sodium salicylate solution was reported. Several factors influencing the synthesis of this aqueous phase were also discussed. A new synthetic dimer (Ⅱ-Ⅷ, Ⅹ), two new complexes of titanocene (ring substituted) were synthesized by the two-phase method of titanium salicylate. The complex Ⅰ was synthesized by two-phase method for the first time. The reaction is shown below:
