| Popis: | Reaction of trimeric 1-benzyl-2-gold(I)-imidazole, Au3im3 (im [μ-(N1-benzyl)imidazolato-N3,C2]) with XY reagents gives either gold(I) mononuclear carbene derivatives, XAuCNRCHCHNY (Y−X = Et-I or EtO(O)CCl) or trinuclear mixed valence or gold(III) compounds. The gold(III) complexes, [(X)(Y)Au]3im3, are formed by addition of X–Y (benzoyl or p-tosyl chloride) or by reaction with thionyl chloride. With iodine and with Me3SiI, Au3im3I2 and Au3im3I4, respectively, are formed. The crystal structure of ClAuCN(CH2Ph)CHCHNCOOEt has been determined. |
