Three diorganotin compounds containing silicon and their phenanthroline complexes have been synthesized.Their structures were characterized by elemental analsis,IR and NMR(1H,13C).The results indicated that in the com...Three diorganotin compounds containing silicon and their phenanthroline complexes have been synthesized.Their structures were characterized by elemental analsis,IR and NMR(1H,13C).The results indicated that in the complexes the two donor N atoms of the ligand coordinate to Sn atom,gave the struture of six-coordinated distorted octahedron.展开更多
Fourteen bis (substituted silylmethylene)tin arylcarboxylates have been synthesized by the reaction of bis(substituted silylmethylene)tin dichloride with arylcarboxylic acids, and characterized by IR, 1H NMR, 13C NMR,...Fourteen bis (substituted silylmethylene)tin arylcarboxylates have been synthesized by the reaction of bis(substituted silylmethylene)tin dichloride with arylcarboxylic acids, and characterized by IR, 1H NMR, 13C NMR, MS and elemental analysis. The preliminary bioassay tests showed that (RMe2SiCH2)2Sn(OOCAr)2 and (RMe2SiCH2)2 SnCl2 had a good antitumour activity in vitro.展开更多
