摘　　要：在H2 O/CHCl3 体系中 ,由 5 磺基水杨酸的存在与否分别合成了茜素红二茂钛配合物 .结果发现 ,5 磺基水杨酸对两相法合成茜素红二茂钛配合物有明显催化作用 .所得化合物经元素分析、IR、X衍射及热重分析等确定了结构 .在配合物结构中 ,茜素红配体中的两个羟基氧均与钛键合 ,形成五元环状二茂钛配合物 。A new alizarin red of titanocene complex is prepared in the presence or in absence of 5 sulfosalicylic acid in H 2O/CHCl 3 medium respectively. It is shown that 5 sulfosalicyclic acid can be used as a catalyst for interfacial method. The compound is characterized by elemental analysis, IR, X ray diffraction and TG analysis. In the structure of the complex, two oxygens of phenol in the ligand are bound to Ti to form a five membered cyclic complex of titanocene. In addition, it contains two molecular water.
