摘要：
A series of cationic imidazolinylidene and thiazolinylidene gold(III) complexes was synthesized by the oxidative addition of halogens to the corresponding bis(carbene) gold(I) compounds. Similar reactions with the thiazolyl-derived mono(carbene) gold(I) complex only give mono(carbene) halogold(I) compounds. Quantum mechanical calculations employing the GAUSSIAN92 series of programs at the DFT/HF (hybrid density functional theory) level were carried out for the model complexes [Au(CNHCH=CHNH}(2)Cl-2](+) and [Au{CNHCH=CHNH}(2))(+) and compared to the molecular structure of the imidazolinylidene gold(III) compound [Au{CNMeCH=CHNMe}(2)Cl-2][CF3SO3] as well as an analogous gold(I) complex.
