2-硒代咪唑啉5是由咪唑-2-亚基4与硒反应得到的,产率非常高。通过NMR和X射线分析揭示了碳硒键(2)的叶立德性质。与相应的碲化合物3相比,碳硫属元素键级在5建议减少。
The 2-selenoimidazolines 5 are obtained from the reaction of the imidazol-2-ylidenes 4 with selenium in very good yields. The ylidic nature of the carbon selenium bond (2) is revealed both by NMR and by X-ray analysis. On comparison with the corresponding tellurium compounds 3, reduction of the carbon chalcogen bond order in 5 is suggested.
