| Popis: | Several new monobutyltin(IV) derivatives containing both oximes and N-protected amino acids have been generated. The compounds having the general formulae BuSn[(L)2A], where LH=cyclohexanoneoxime, acetophenoneoxime and (where R=-CH(CH3)2, -CH(CH3)CH2CH3, -CH2C6H5), and BuSn[L(A)2], where LH=cyclohexanoneoxime, acetophenoneoxime and (where R=-CH(CH3)2, -CH(CH3)CH2CH3, -CH2C6H5), were generated by the reactions of monobutyltin(IV) trichloride with sodium salts of oximes and N-protected amino acids in 1:2:1 and 1:1:2 molar ratios in dry boiling benzene. Plausible structures of these compounds were suggested based on physico-chemical and spectroscopic studies. 119Sn NMR spectroscopic data revealed the presence of five and six coordinated tin centers. |
