摘要: 用2种新的膦配体N,N′-二[(二苯基膦)亚甲基]-N,N′-二(4-吡啶甲基)-对苯二胺(L1)和N,N′-二[(二苯基膦)亚甲基]-N,N′-二(2-吡啶甲基)-对萘二胺(L2),与金盐[AuCl(THF)](THF=四氢呋喃)反应生成有机膦氯化金配合物;该配合物进一步在苯乙炔的作用下生成有机膦金炔配合物;金炔配合物与叠氮基三甲基硅烷反应得到三氮唑配合物。通过红外、核磁和X-射线单晶衍射对这些配合物进行表征,发现配合物中弱的Au-π作用对配合物的稳定性起着一定的作用。

Abstract: Reaction of two new phosphine ligands, N, N′-bis [(diphenylphosphine) methylene]-N, N′-bis(4-pyridine methyl)-p-phenylenediamine (L1) and N, N′-bis[(diphenylphosphine) methylene]-N, N′-bis(2-pyridine methyl)-p-naphthalene diamine (L2), with gold salts [AuCl(THF)] (THF = tetrahydrofuran) produced organic phosphine gold chloride complexes. Then, it generated organic phosphonic alkyne complexes of gold by further treatment with phenylacetylene. The obtained gold alkyne complexes reacted with trimethylsilane azide to generate 1, 2, 3-triazoles complexes. These complexes were characterized by infrared spectrum, nuclear magnetic spectrum and X-ray single crystal diffraction. It was found that the weak Au-π interactions play a certain role in the stability of the complexes.

Key words: phosphine ligand, phosphine-gold complexes, synthesis, crystal structures, Au-π interactions
