Characterization of mono(carbene) and bis(carbene) complexes of gold(I) derived from lithiated pyridine
摘要:
The carbene complexes [Au(CNHCH=CHCH=CH)Cl] (2) and [Au(CN(R)CH=CHCH=CH)(2)][X] (R = H, X = Cl (4)) (R = Me, X = CF3SO3 (5)) are formed when the products of the reactions between [Au(THT)Cl] (THT = tetrahydrothiophene) and 2-lithiopyridine are acidified with HCl or alkylated with CF(3)SO(3)Me. Compound 4 crystallizes with two molecules of H2O. The complex is monomeric and interacts with the water molecules and the chloride ion through a complex network of hydrogen bonds.
