S^S)-cyclometallated gold(III) complexes of general formula [Au(dppta)(azmtd)] (azmdt = azol(in)ium-2-(methoxy)methanedithiol-κ2S,S) 28–34. All the [Au(dppta)(azdtc)Cl] complexes 21–27 catalyzed the alkylation of indoles, whereas [Au(dppta)(azmtd)] complexes 28–34 were inactive. Among the synthesized derivatives, complex 22 displayed the highest catalytic activity, leading to a series of functionalized
一系列环金属化金( III )配合物21–27 ,通式为 [Au(dppta)(azdtc)Cl] (dppta = N , N -二异丙基- P , P -二苯基硫代膦酰胺-κ 2 C,S; azdtc = 唑(in)ium-2-二硫代羧酸盐-κ 1 S)通过光谱和衍射技术进行制备和表征。用甲醇处理 [Au(dppta)(azdtc)Cl] 配合物,使其定量转化为通式为 [Au(dppta)( azmtd)] (azmdt = azol(in)ium-2-(甲氧基)甲烷二硫醇-κ 2 S,S) 28–34 。所有[Au(dppta)(azdtc)Cl]配合物21-27都催化吲哚的烷基化,而[Au(dppta)(azmtd)]配合物28-34没有活性。在合成的衍生物中,配合物22表现出最高的催化活性,以优异的产率产生了一系列功能化吲哚。
