摘要:
(C6H5)3SnOH和C6H5SO3H通过回流反应合成了有机锡复合物［(C6H5)3SnOS(O)2(C6H5)］n，并采用元素分析、IR和X射线单晶衍射对其进行了表征.结果表明:化合物属单斜晶系，空间群P21/n，晶胞参数a=0.689 0(1) nm，b=1.637 1(3) nm，c=1.937 6(2) nm，β=96.379(9)°，V=2.172 0(6) nm-3，Z=4；它是通过苯磺基的桥联而形成的一维链状聚合物，且配合物的锡原子呈略微畸变的五配位三角双锥构型；当其催化碳酸二甲酯与苯酚酯交换合成碳酸二苯酯时，受苯磺基空间位阻效应的影响，其催化活性较低，碳酸二甲酯的转化率仅为7.2%.
Abstract:
The organotin complex ［(C6H5)3SnOS(O)2(C6H5)］n was synthesized by the reflux reaction of (C6H5)3SnOH with(C6H5SO3H and determined by elemental analysis, IR and Xray diffraction single crystal structure analysis. The results show that the crystal belongs to monoclinic, space group P21/n with a=0.689 0(1) nm，b=1.637 1(3) nm，c=1.937 6(2) nm，β=96.379(9)°，V=2.172 0(6) nm3，Z=4.The compound is a onedimensional chained polymer by virtue of the bridging benzenesulfonate groups, and the tin atom is fivecoordinated in a slightly distorted trigonal bipyramidal configuration. When it catalyzed the transesterification of dimethyl carbonate and phenol to diphenyl carbonate, it showed the very low catalytic activity due to the steric hindrance effect of the benzenesulfonate, and the conversion of dimethyl carbonate was only 7.2%.
