biscarbenes, 1,4- and 1,3-bis[1-(1-adamantyl)-3-phenyl-1,2,4-triazol-5-yliden-4-yl]benzenes (4a,b) have been prepared. Treatment of 4b with copper(I) chloride and copper(I) iodide in acetonitrile or acetonitrile/toluene solution afforded the biscarbene copper(I) complexes 5a and 5b, respectively. The reactions of 4a and 4b with diphenyldiazomethane and sulfur resulted in the novel bisazine (6) and
稳定的双卡宾,1,4-和1,3-双[1-(1-金刚烷基)-3-苯基-1,2,4-三唑-5-亚胺基-4-基]苯(4a,b)具有准备好了。在乙腈或乙腈/甲苯溶液中用氯化铜(I)和碘化铜(I)处理4b,分别得到双卡宾铜(I)配合物5a和5b。4a和4b与二苯基重氮甲烷和硫的反应分别产生了新的双嗪(6)和双硫酮(7)衍生物。确定了4a和5b的X射线晶体结构。
