| 摘要: 以双三苄基氧化锡([(PhCH2)3Sn]2O)和苯磺酸(PhSO3H)为原料合成了新的二苄基锡苯磺酸酯(PhCH2)2Sn(OS(O)2Ph)2(H2O)2，并采用红外光谱、元素分析和X射线单晶衍射对其结构进行了分析。该化合物的晶体结构属单斜晶系，空间群为P21/c，晶胞参数a=1.458 71(8) nm，b=1.178 21(8) nm，c=0.758 18(4) nm，β=92.393(2)°，V=1.301 92(13) nm-3，Z=2；化合物中所有的锡原子均为略微畸变的八面体构型。当(PhCH2)2Sn(OS(O)2Ph)2(H2O)2催化碳酸二甲酯与苯酚酯交换合成碳酸二苯酯时，碳酸二甲酯的转化率可达55.8%，酯交换选择性接近100%。 | |

| Abstract: A new dibenzyltin phenylsulfonate, (PhCH2)2Sn(OS(O)2Ph)2(H2O)2, has been synthesized by the reaction of [(PhCH2)3Sn]2O with PhSO3H, and characterized by infrared spectrum, elemental analysis and X-ray diffraction single crystal structure analysis. The complex belongs to monoclinic, space group P21/c with a=1.458 71(8) nm, b=1.178 21(8) nm, c=0.758 18(4) nm, β=92.393(2)°, V=1.301 92(13) nm-3, Z=2. In the complex, each tin atom is six-coordinated with a slightly distorted octahedral geometry. When (PhCH2)2Sn(OS(O)2Ph)2(H2O)2 catalyzed the transesterification of dimethyl carbonate and phenol to synthesize diphenyl carbonate, the conversion of dimethyl carbonate was up to 55.8% with a close 100% transesterification selectivity.
