(β-Carboalkoxyethyl)tin trihalides and bis(β-carboalkoxyethyl)tin dihalides react with metallic zinc to give mixtures of the corresponding tris(β-carboalkoxyethyl)tinhalides and the tetra(β-carboalkoxyethyl)tins. Bis(β-carboalkoxyethyl)tin diacetates react with metallic zinc to give only the corresponding tetra(β-carboalkoxyethyl)tincompounds. The mechanisms of these reactions are discussed. Conversion
Hybrid organic/inorganic Wells-Dawson polyoxotungstates have been prepared throughaddition of functionalized tricholorostannanes to lacunary alpha(2)- and alpha(1)-[P(2)W(17)O(61)](10-). Coupling of amines and alcohols to polyoxotungstate platforms led to new structures in good yields. Coupling of chiral amines to the previously unknown organotin-substituted alpha(1) derivatives allowed the isolation
混合有机/无机 Wells-Dawson 聚氧钨酸盐已通过将功能化的三氯锡烷添加到缺孔 alpha(2)-和 alpha(1)-[P(2)W(17)O(61)](10-) 中制备。胺和醇与聚氧钨酸盐平台的偶联以良好的收率产生了新的结构。手性胺与以前未知的有机锡取代的 alpha(1) 衍生物的偶联允许分离非对映异构体,在某些情况下,其特征是分裂 (1) H、(13) C 和 (31) P NMR 光谱。这是 alpha(1)-Wells-Dawson 系列中一对非对映异构体的 NMR 观察的第一个例子。它为那些手性多氧钨酸盐的潜在分辨率开辟了道路。

A series of anionic monoorgano-pentahalogenostannate(IV) complexes, M+2[RSnX5]2−, where M = K+, Me4N+, Et4N+ or MePPh3+; X = F, Cl or Br; R = Bu, Ph or R′OCOCH2CH2 (R′ = Me or Et), has been prepared and these compounds have been studied by 119mSn Mössbauer spectroscopy. The novel monoorgano-tetrachlorostannate salts, Me4N+ [R′OCOCH2CH2SnCl4]−, where R′ = Et, Pr, i-Pr or Bu, have been synthesised and
