A study of the syntheses and some properties of several methyl substituted acyclic and cyclic bidentate organotin Lewis acids has been carried out. Of particular interest were cyclic species with 7-, 8-, 9- and 10-membered rings. The distannaalkanes and distannacycloalkanes were converted to the chlorides by chlorodemethylation with tin chlorides or mercuric chloride; this reaction was accompanied
已经进行了几种甲基取代的无环和环状二齿有机锡路易斯酸的合成和一些性质的研究。特别令人感兴趣的是具有7、8、9和10元环的环状物质。通过用氯化锡或氯化汞进行氯脱甲基化,将二烷烷和二烷环烷烃转化为氯化物。在某些情况下,该反应伴有环断裂。反过来,氯化物很容易转化为甲磺酸盐和三氟甲磺酸盐。1 H,13 C和119 Sn NMR和IR光谱数据用于获得有关结构,构象和聚集行为的信息。甲磺酸酯在氯仿中缔合。三叉戟不是。
