All compounds were characterized by elemental analysis, IR, 1H NMR and MS. The results showed that bis(triphenylgermanium) alkynyl or alkenyl phosphonates are both four- and five-coordinated germanium and triphenylgermanium alkynyl or alkenyl phosphonates are five-coordinated germanium.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
Six novel tribenzyltin(IV) dervatives of alkynyl or alkenyl Phosphonic acid (PhCH2)3SnOP(O)(OH)R, Where R=C≡CPh, C≡CC3H7 n,C≡CC4H9 n, C≡CC5H11 n,C≡CC6H13 n, CH=CClPh,were synthesized by resaction of the monosodiu...Six novel tribenzyltin(IV) dervatives of alkynyl or alkenyl Phosphonic acid (PhCH2)3SnOP(O)(OH)R, Where R=C≡CPh, C≡CC3H7 n,C≡CC4H9 n, C≡CC5H11 n,C≡CC6H13 n, CH=CClPh,were synthesized by resaction of the monosodium salt of the alkynyl or alkenyl phosphonic acid with tribenzyltin(IV) chloride in benzene. Their structures were cheracterized by elementary analysis, IR,1H NMR, 119Sn NMR, MS and TG DTA. The results showed that these compounds arefive coordinated -O-P-O-bridged polymers.展开更多
