In the presence of 8-hydroxyquinoline, five titanocene substituted salicylato complexes were prepared in aqueous or H2O/CHCl3 medium, respectively. The complexes were characterized by elemental analysis, IRand 1H NMR spectra. The results show that substituted salicylic acid actsas a bidentate ligand and coordinates with Ti to form a cyclic compound. In addition, the structure of the complexes does not contain 8-hydroxyquinoline ligand. Based on the UV-vis spectrum, the mechanism of the reaction was proposed: 8-hydroxyquinoline in the aqueous phase and Cp2TiCl2 in the organic phase form an aqueous-complex-8-hydroxyquinoline titanocene complex interfacially, then, the aqueous-complex undergoes a ligand exchange with substituted salicylic acid to form the final complexes.

Key words: 8-hydroxyquinoline, titanocene complex, substitutedsalicylic acid, water-phase method, two-phase method
