  The synthesis and ir and NMR (1HH, 3CC AND 9Sn)Sn) spectral studies of some methyltin(IV) sulphonates

  摘要：

  Some methyltin(IV) sulphonates, Me(n)Sn(OSO(2)X)(4-n) (n = 1-3 and X = 4-tolyl and 2-naphthyl) have been prepared. The H-1, C-13 and Sn-119 NMR spectra of these compounds and the previously reported compounds, Me(3)Sn(OSO(2)X) (X = CF3, CH3 and 4-CH3C6H4) and Me(2)Sn(OSO2CH3)(2), in coordinating and non-coordinating solvents have been studied. From the chemical shifts delta(Sn-119) and the coupling constants (1)J(C-13, Sn-119) and (2)J(H-1, Sn-119), coordination number of the tin atom and the geometry of its coordination sphere have been suggested. These observations have been complemented by IR spectroscopy. Synthesis of the ternary compounds, MeSnCl(OSO(2)X)(2) (X = CH3 and 4-CH3C6H4), by reaction between Me(3)Sn(OSO(2)X) and Me(2)SnCl(2) and subsequent cleavage of the tin-carbon bond is also discussed.

  摘要：

  由于其强大的亲电特性，三氧化硫可以插入碳与硅，锗，锡和铅元素之间的键中。该反应在非常温和的条件下进行，通常得到磺酸的有机金属衍生物，R 3 M ＝OSO 2 R（M ＝ Si，Ge，Sn和Pb； R ＝烷基或芳基）。在合适的条件下，可以检测到有机金属硫酸盐和磺酸酐（R 3 MO）2 SO 2和RSO 2 OSO 2 R作为副反应的产物。描述了所得产物的性质并讨论了反应机理。

  Due to its strong electrophilic character sulfur trioxide can be inserted in bonds between carbon and the elements silicium, germanium, tin and lead. This reaction takes place under very mild conditions and in general yields organometallic derivatives of sulfonic acids, R3MOSO2R (M = Si, Ge, Sn and Pb; R = alkyl or aryl). Under suitable conditions organometal sulfates and sulfonic acid anhydrides
