Abstract


So many research works proved that diorganotin compounds have obvious antitumour activity, and their activity depends on the alkyls and ligands. The activity of asymmetric diorganotin containing silicon will be reserved while the toxicity can be reduced. Study on mixed diorganotin compounds containing silicon is of some realistic significance to researching the biological active of organotin whose certain C actom is substituted by a silicon actom. In order to study the relation between structure and the characterization of organotin systemically, diorganotin compounds were synthetized in this paper.(1) R1(EtMe2SiCH2)SnCl2(2) R1(EtMe2SiCH2)Sn0(3) n-Bu(EtMe2SiCH2)Sn(OCOAr)2(4)n-Bu(EtMe2SiCH2)Sn[2,6-Py(CO2)2](5) (EtMe2SiCH2)2Sn(OCOC5H4N-m)2(6) (EtMe2SiCH2)2SnCl2(Phen) R]= n-Bu, Cy, Ph, EtMe2SiCH2 Ar=-C6H4-H,-C6H4-F-p,-C6H4-CH3-p,-C6H4-OCH3-o,-C6H4-Cl-oTheir structures were characterized by IR,1H NMR,13C NMR and elementary analysis. The results showed that the Sn atom of butyl (ethyldimethylsilylmethyl) tin arylcarboxylates, and diorganotin phenanthroline comlexes containing silicon is probably in a six-coordinated distorted octahedron, while diorganotin pyridine carboxylate may be formed molecules of nitrogen tin coordination and the Sn atom of dialkyltin 2,6-pyridinedicarboxylates containing silicon may be in a five-coordinated trigonal bipyramind.
