p-nitrobenzyl bromide (2), symmetrically and non-symmetrically p-nitrobenzyl-substituted N-heterocyclic carbene (NHC) [(3a–f)] precursors were synthesised. These NHC-precursors were then reacted with silver(I) acetate to yield the NHC-silver acetate complexes [1,3-bis(4-nitrobenzyl)imidazol-2-ylidene]silver(I) acetate (4a), [4,5-dichloro-1,3-bis(4-nitrobenzyl)imidazol-2-ylidene]silver(I) acetate (4b), [1,3-bis
来自 1H-咪唑 (1a)、4,5-二氯-1H-咪唑 (1b)、1H-苯并咪唑 (1c)、1-甲基咪唑 (1d)、4,5-二氯-1-甲基咪唑 (1e) 的反应和 1-甲基苯并咪唑 (1f) 与对硝基苄基溴 (2)、对称和非对称对硝基苄基取代的 N-杂环卡宾 (NHC) [(3a-f)] 前体合成。然后将这些 NHC-前体与乙酸银 (I) 反应,得到 NHC-乙酸银复合物 [1,3-双(4-硝基苄基)咪唑-2-亚基] 乙酸银 (I) (4a), [4, 5-二氯-1,3-双(4-硝基苄基)咪唑-2-亚基]银(I)醋酸盐(4b),[1,3-双(4-硝基苄基)苯并咪唑-2-亚基]银(I)醋酸盐 (4c), [1-methyl-3-(4-nitrobenzyl)imidazole-2-ylidene] 醋酸银 (I) (4d), [4, 5-dichloro-1-methyl-3-(4-nitro
