含有机膦金炔三氮唑配合物的合成表征及晶体结构

Synthesis,Characterization and Crystal Structures of Complexes Containing Organic Phosphine Gold Acetylene and Triazoles

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。

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-πinteractions play a certain role in the stability of the complexes.
