Two neutral bis(pentafluorophenyl)thiolate gold(III) complexes with the unsymmetrical S^N ligands 2-aminothiophenol or cysteamine have been synthesized and their reactivity has been studied. Homo- and heterodinuclear compounds were obtained by their coordination to gold(I) or silver(I) derivatives through the sulfur atom. Interestingly, a tetranuclear derivative bearing short gold(I)···gold(I) and the more unusual gold(I)···gold(III) interactions has been prepared. These amino-thiolate derivatives can be used as precursors for the synthesis of novel gold(III) acyclic diaminocarbene complexes by reaction with isocyanides CNR. The nucleophilic attack of the amino group to isocyanide molecules affords the synthesis of unprecedented bidentate C^S acyclic diaminocarbene ligands. All of the complexes are air- and moisture-stable at room temperature and have been spectroscopically and structurally characterized.
已合成了两种带有不对称S^N配体2-氨基硫酚或半胱胺的中性双（五氟苯基）硫醇金（III）配合物，并对其反应活性进行了研究。通过硫原子与金（I）或银（I）衍生物配位得到了同核和异核化合物。有趣的是，制备了一种具有短金（I）···金（I）以及更不寻常的金（I）···金（III）相互作用的四核衍生物。这些氨基硫醇盐衍生物可通过与异腈CNR反应用作合成新型金（III）无环二氨基卡宾配合物的前体。氨基对异腈分子的亲核进攻实现了前所未有的双齿C^S无环二氨基卡宾配体的合成。所有配合物在室温下对空气和湿气稳定，并已通过光谱和结构表征。
