A procedure for the synthesis of three‐dimensional hexakisimidazolium cage compounds has been developed. The reaction of the trigonal trisimidazolium salts H3L(PF6)3, decorated with three N‐olefinic pendants, and silver oxide yielded trinuclear trisilver(I) hexacarbene molecular cylinders of the type [Ag3L2]3+ with the olefinic pendants from the two different tricarbene ligands arranged in three pairs
已经开发了合成三维六氮杂咪唑笼状化合物的方法。带有三个N-烯烃侧基的三方形三咪唑鎓盐H 3 L(PF 6)3与氧化银的反应产生了[Ag 3 L 2 ] 3+类型的三核三银(I)六碳烯分子圆柱体来自两个不同的三碳烯配体的烯属侧链排列成三对。随后的紫外线照射在三个[2 + 2]环加成反应中在两个tris-NHC配体之间产生了三个环丁烷键,从而生成了三维六-NHC配体。金属离子的去除导致形成具有大内部空腔的三维六亚基咪唑笼。
