摘要

The synthesis of the macrocyclic tetraimidazolium salt (H _4-1)(Br)_4 and the anion exchange to (H_4-1) (PF_6)_4 have been explored. Deprotonation of (H _4-1)(PF_6)_4 with Ag_2O yields the mono- and dinuclear silver(i) complexes [Ag(H_2-1)](PF _6)_3 and [Ag_2(1)](PF_6)_2. Transmetallation of the dicarbene and tetracarbene ligands to gold(i) yields the mono- and dinuclear gold(i) complexes [Au(H_2-1)](PF _6)_3 and [Au_2(1)](PF_6)_2. The monosilver complex [Ag(H_2-1)](PF_6)_3, featuring two imidazolium moieties, has been deprotonated and used for the synthesis of the tetranuclear silver(i) octacarbene complex [{Ag(1)} _2Ag_2](PF_6)_4.
