| 中文摘要: |
| 采用铂替代钯合成了以二叔丁基苯基膦[(t-Bu)2PPh]和卤素(Cl、Br)为配体的Pt(II)配合物。以氯化铂(PtCl2)和溴化铂(PtBr2)为起始原料，二甲亚砜(DMSO)为溶剂，在氮气保护下与二叔丁基苯基膦反应，得到目标化合物。结果表明，Pt[(t-Bu)2PPh]2Cl2产率为96.9%，Pt[(t-Bu)2PPh]2Br2产率为94.1%，2种化合物的纯度均大于99%。通过元素分析、核磁共振(1H-NMR)分析和单晶X射线衍射(XRD)分析测定了目标化合物的化学结构，结果显示，配合物均为trans-四配位的平面正方形配合物，Pt(II)处于配位平面的中心，分别与2个Cl或者Br和P键合，形成4配位的平面四边形的结构，2个卤素原子和膦配体处于反位。 |
| 英文摘要: |
| Two new platinum complexes, Pt[(t-Bu)2PPh]2X2 (X=Cl, Br) were synthesized using platinum chloride (PtCl2), platinum bromide (PtBr2) and di-tert-butyl phenyl phosphine as starting materials, dimethyl sulfoxide (DMSO) as a solvent under nitrogen protection. Their structures were characterized by MS, NMR and X-ray single-crystal diffraction analysis. The results showed that the yield of Pt[(t-Bu)2PPh]2Cl2 was 96.9%, and that the yield of Pt[(t-Bu)2PPh]2Br2 was 94%. The purity of the two compounds was greater than 99%. The structure analysis results showed that the complexes were all trans- four-coordinated planar square complexes where Pt(II) locates in the center of the coordination plane, bonds with 2 Cl or Br and P respectively, and 2 halogen atoms and the phosphine ligand are in the anti-position. |
