Synthesis, Structural Analyses And Antibacterial Activities Of New Non-Functionalized And Nitrile-Functionalized Silver(I) N-Heterocyclic Carbene Complexes

Dua siri baru garam benzimidazolium benzil bergantian iaitu bukan berfungsi (1-3·PF6 and 7-9·2PF6) dan berfungsian nitril (4-6·PF6 and 10-12·2PF6) telah berjaya di sintesis sebagai pelopor untuk N-heterosiklik karbena (NHC). Tindak balas antara garam benzimidazolium dan argentum(I) oksida dengan kad...

Tindak balas antara garam benzimidazolium dan argentum(I) oksida dengan kadar bersesuaian telah memudahkan garam benzimidazolium untuk berdeprotonasi in situ yang mendapatkan dua siri kompleks argentum(I)-NHC, [Agn(L)2]·nPF6 (Ag1-Ag12), masing-masing (di mana L = 1-6: 1-(2’/3’/4’-metilbenzil/metilbenzonitril)-3-(2’’-propil)benzimidazolium, n = 1 atau L = 7-12: 3,3-(butana-1,4-diyl)-1,1-(2’/3’/4’-metilbenzil/metilbenzonitril)bisbenzimidazolium, n = 2).

The reaction of an appropriate ratio of respective benzimidazolium salts with silver(I) oxide facilitated the in situ deprotonation of the benzimidazolium salts that afforded the formation of two series of silver(I)-NHC complexes, [Agn(L)2]·nPF6 (Ag1-Ag12), (where L = 1-6: 1-(2’/3’/4’-methylbenzyl/methylbenzonitrile)-3-(2’’-propyl)benzimidazolium, n = 1 or L = 7-12: 3,3-(butane-1,4-diyl)-1,1-(2’/3’/4’-methylbenzyl/methylbenzonitrile)bisbenzimidazolium, n = 2).
