三环己基锡芳氧乙酸盐的合成及其结构表征 总被引:4,自引:0,他引:4
三环己基锡衍生物(Cy_3SnX,Cy=环己基,X=配体或取代基)是一类具有较强生物活性的有机锡化合物,它们广泛用作杀螨剂,杀菌剂和海洋防污剂。有关三环己基锡芳氧乙酸盐的合成至今报道很少。Bubblitz 合成了两个三环已基锡芳氧乙酸盐,此后,Matsuda 等人制备了三环已基锡-2,4-二氯苯氧乙酸盐,它们都具有良好的杀螨、杀菌活性,后者还可应用于海洋 相似文献

In the previous paper(Ⅲ), the following equation of solvent effect in organic chemistry was suggested:
Ei=a﹒Ai(1-Va﹒VAi)+d﹒Di(1-Vd﹒VDi)+E0
Where Ei is a physical or chemical property of the substrate in the solvent i and E0 is that in n-hexane. Ai and Di are constants of electron acception and donation effect of the solvent i respectively. VAi and VDi are constants of electron acception and donation space effect of the solvent i respectively, a and d are the sensitivities of E of the substrate vs the change of Ai and Di. Va and Vd are the constants of electron acception and donation space effect of the substrate respectively. In IR spectra E could be substituted by the wavenumber(ν). Ai and VAi have been established for 18 organic solvents (n-C6H14, n-C7H16, cyclohexane, CCl4, Ph-Me, ClCH:CCl2, Et2O, CHCl3, C6H6, CH2Cl2, ClCH2CH2Cl, Ph-NO2, THF, 1,4-dioxane, Et-NO2. MeCO2Et, Me-NO2, Me-CN).
In this paper Di and VDi have been established for these solvents. The equation also has been tested by the νC-X(X=Cl, Br) of five alkylhalides (t-BuCl, n-C5H11Cl, t-BuBr, Et-Br, EtC(H)BrMe) and νC=O of three carboxyl compounds (t-BuCOMe, Me2CO, MHB) and seven organotin compounds [(Ph2MeSiCH2)3SnO2C-C6H4-X-p(X=H-, CH3-, CH3O-, NO2-, F-. Cl-, I-)].
The relationship (ν=ρ﹒σ+ν0) between νC=O of organotin compounds and Hammett constants(σ) of the substituted groups in different solvents was studied and a relationship betweenρ and Ai, VAi, Di, VDi of the solvents was found. 相似文献

三环己基羧酸锡的分子结构和晶体结构 总被引:3,自引:0,他引:3
用单晶X射线衍射技术测定了三个三环己基羧酸锡化合物—三环己基丁酸锡(1), 三环己基-间氯代苯甲酸锡(2), 三环己基-间溴代苯甲酸锡(3)的分子和晶体结构. 三种化合物均属正交晶系, 空间群分别为P212121(1), Pnaa(2), Pnaa(3). 1的晶胞参数为:a=9.963(2), b=11.004(3), c=20.144(6)埃, Z=4. 2的晶胞参数为: a=8.135(2),b=16.716(3), c=36.426(6)埃, Z=8. 3的昌胞参数为: a=8.165(1), b=16.714(3),c=36.710(4)埃, Z=8. 在1的晶体中, 锡原子呈五配位的三角双锥构型. 桥联的羧基使其结构成为含有两种不同Sn-O键(2.198(4)和2.427(3)埃)的线型聚合物. 2和3的晶体则是由孤立的分子所组成. 在每个分子中, 四配位的锡原子呈畸变的四面体构型, 羧基不能象在化合物1中那样在锡原子之间成桥, 可能主要是由于环己基与卤代苯甲酸根之间的空间位阻效应所致. 相似文献
