杂环有机锡化合物的谱学表征(英文)

SPECTRAL CHARACTERIZATION OF HETEROCYCLIC ORGANOTIN( Ⅳ) COMPOUNDS

合成了八个杂环芳基正丁基有机锡化合物,它们的通式是RnSnBu_((4-n))(R=2-呋喃基或2-噻吩基,n=l,2,3;R=2-(N-甲基)吡咯基或2-吡啶基,n=l)。其中二正丁基-二(2-呋喃基)锡、正丁基-三(2-呋喃基)锡、二正丁基-二(2-噻吩基)锡和正丁基-三(2-噻吩基)锡是新化合物。这些化合物都经过了元素分析和~1H、^(13)C和^(119)Sn NMR及IR谱表征,文中重点讨论了它们的谱学特征。

Eight heterocyclic aryl n-butyltin (Ⅳ) compounds are synthesized. The general formula is Rn-SnBu(4-n)(R = 2-furyl or 2-thienyl, n = l,2,3; R = 2 -( N-methyl) pyrrolyl or 2 -pyridyl, n = l). Four of them are novel compounds : dibutyl di(2-furyl) tin, butyltri ( 2-furyl)tin, dibutyl di( 2 -thienyl) tin and butyl tri( 2 - thicnyl) tin. Their structures are characterized by elementary analysis, IR and NMR etc. The spectral features are discussed.
