metal−carbene complexes. Reaction of the zwitterionic imidazolium compounds with Ag2O gave bis(imidazol-2-ylidene)silver complexes. These compounds have been characterized spectroscopically and by electrospray mass spectrometry. A DMSO solvate of bis[1-(2,6-diisopropylphenyl)-3-(3-sulfonatopropyl)imidazol-2-ylidene]silver sodium salt has been structurally characterized. In the solid state, this complex exists
已经合成了带有烷基磺酸盐和烷基羧酸盐取代基的两性离子咪唑鎓盐,并用作水溶性金属-碳烯络合物的前体。两性离子咪唑化合物与Ag 2的反应O给出双(咪唑-2-亚烷基)银配合物。这些化合物已经在光谱学上和通过电喷雾质谱法进行了表征。在结构上已表征了双[1-(2,6-二异丙基苯基)-3-(3-磺酰基丙基)咪唑-2-亚甲基]银钠盐的DMSO溶剂化物。在固体状态下,该络合物作为配位聚合物存在,其中钠离子桥接两个双(咪唑-2-亚甲基)银基团的磺酸盐基团。还已经以低收率制备了二碘代双[1-甲磺酰基-3-(3-磺酰基丙基)咪唑-2-亚丙基]钯二钠盐,并通过NMR光谱和电喷雾质谱法对其进行了表征。
