《Isolable, gold carbonyl complexes supported by N-heterocyclic carbenes》 was published in Chemical Communications (Cambridge, United Kingdom) in 2011. These research results belong to Dash, Chandrakanta; Kroll, Peter; Yousufuddin, Muhammed; Dias, H. V. Rasika. Safety of Chloro{1,3-bis[2,6-bis(1-methylethyl)phenyl]-4,5-dihydroimidazol-2-ylidene}gold(I) The article mentions the following:
Cationic gold carbonyl complexes supported by N-heterocyclic carbene ligands, 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene (SIDipp) and 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IDipp), have been synthesized. [(SIDipp)Au(CO)][SbF6] has a linear, two-coordinate gold center. [(SIDipp)Au(CO)][SbF6] and [(IDipp)Au(CO)][SbF6] display νCO values at 2197 and 2193 cm-1, resp. Computational studies on [(SIMe)Au(CO)]+ indicate the presence of a strong Au(I)-CO bond. The experimental part of the paper was very detailed, including the reaction process of Chloro{1,3-bis[2,6-bis(1-methylethyl)phenyl]-4,5-dihydroimidazol-2-ylidene}gold(I)(cas: 852445-84-2Safety of Chloro{1,3-bis[2,6-bis(1-methylethyl)phenyl]-4,5-dihydroimidazol-2-ylidene}gold(I))
Chloro{1,3-bis[2,6-bis(1-methylethyl)phenyl]-4,5-dihydroimidazol-2-ylidene}gold(I)(cas: 852445-84-2) belongs to imidazoles.Imidazole rings are part of unnatural cyclic peptides and are used as ester isosteres in peptidomimetic studies.
Safety of Chloro{1,3-bis[2,6-bis(1-methylethyl)phenyl]-4,5-dihydroimidazol-2-ylidene}gold(I) However, the application of imidazoles is not limited to the field of peptides and peptidomimetics.
