Abstract


The organic tin compound has been widely used insecticides, marine coatings, PVC plastic heat stabilizer, as well as in organic reactions homogeneous catalyst. Since organotin complexes was found to have strong anti-cancer activity, its synthesis and biological activity of attention in recent years, the gradual emergence of the organotin compounds used as the anion recognition carrier substances reported metal organic chemical cross and the newly developed chemical sensors multidisciplinary research field with great prospects for development. In this paper, tribenzyl tin chloride, triphenyl tin chloride, and dibenzyl tin chloride as raw materials, respectively, and o-hydroxybenzaldehyde, 2,4 - dihydroxybenzaldehyde, 2 - hydroxy-3 - methoxy benzaldehyde, o-hydroxyacetophenone, of 2,4 - Dihydroxyacetophenone acetoacetyl ferrocene reaction synthesis of 16 novel heterocyclic organic tin (IV) complexes, which some substances the anion recognition performance, mainly includes the following four parts: (1) the three benzyl chloride and o-hydroxybenzaldehyde, 2,4 - hydroxybenzaldehyde, 2 - hydroxy-3 - methoxybenzaldehyde, o hydroxyacetophenone, 2,4 - dihydroxyphenyl ethanone bidentate ligand reaction, synthesis of five new five-coordinated heterocyclic benzyl tin (IV) compounds, and its structure was confirmed by elemental analysis, infrared spectroscopy, nuclear magnetic resonance NMR and mass spectrometry test method is confirmed. Its anion response behavior analysis and comparative study of the carrier structure of the electrode response performance. (2) triphenyl tin chloride and o-hydroxybenzaldehyde, 2,4 - dihydroxybenzaldehyde, 2 - hydroxy - 3 - methoxybenzaldehyde, o-hydroxyphenyl ethyl ketone, 2,4 - dihydroxybenzene reaction of the the ethanone bidentate ligand synthesis of five new five-coordinated heterocyclic phenyl tin (IV) compounds, and its structure was confirmed by elemental analysis, infrared spectroscopy, NMR and mass spectrometry test method is confirmed. (3) through dibenzyl tin dichloride and a bidentate ligand of the ratio of 1:2 the amount of material, to synthesize a bis (o-hydroxybenzaldehyde) co-, dibenzyl tin (IV), bis (2, 4 - dihydroxybenzaldehyde) Hop dibenzyl tin (IV) bis (2 - hydroxy-3 - methoxybenzaldehyde) Weli benzyl tin (IV), bis (o-hydroxyacetophenone) together dibenzyl the base tin (IV) bis (2,4 - dihydroxyphenyl ethyl ketone) Weli benzyl tin (IV) five six the coordinated heterocyclic benzyl tin (IV) compounds. Its structure was confirmed by elemental analysis, infrared spectroscopy, NMR and mass spectrometry corroborated. (4) ferrocene to synthesize acetyl ferrocene as the starting material with acetic anhydride, and then reacted with ethyl acetate to give acetoacetyl ferrocene. Acetyl acetyl ferrocene ferroalloys three benzyl tin (IV) with a three-benzyl chloride, tin reaction synthesized a novel five-coordinate bit dual-core organotin complexes. Its structure was confirmed by elemental analysis, infrared spectroscopy, NMR and mass spectrometry corroborated. Anion response behavior of complexes based carrier and examine the of different plasticizers electrode salicylic acid ions in response to the impact of the performance, and the buffer system and solution pH value of the performance of the electrode response. Will based on the acetoacetyl ferrocene aggregate Tribenzyltin for the carrier electrode used in drug analysis, and achieved satisfactory results.
