A comparison of versatile counter anions was investigated by means of a variety of well‐known test reactions representing the key reactivity patterns of homogeneous gold catalysis, the catalytic activity was monitored by GC and ¹H NMR. As previously reported, the counter anion influence is usually more pronounced than the corresponding ligand effect. Due to this, the study is focused on the investigation of counter anions so far not included from investigation of homogeneous gold‐catalyzed reactions. The examinations using so far neglected counter anions (BAr^F₄)⁻, [B(C₆F₅)₄]⁻, [Al(OC(CF₃)₃)₄]⁻ and [B(C₆F₅)₃(OAc^F)]⁻ showed surpassing or at least similar catalytic activities as the commonly used counter anions. The expanded use of counter anions can occupy an important role in future concerning catalyst optimization in gold catalysis.

金催化中抗衡阴离子的工业视角：关于替代抗衡阴离子的研究

通过多种代表均相金催化关键反应模式的众所周知的测试反应，研究了多用途抗衡阴离子的比较，并通过GC和¹ H NMR监测了催化活性。如前所述，抗衡阴离子的影响通常比相应的配体效应更为明显。因此，本研究的重点是迄今为止对均金催化反应的研究中还没有包括的抗衡阴离子的研究。使用到目前为止被忽略的抗衡阴离子（BAr ^F₄）^-，[B（C ₆ F ₅）₄ ] ^-，[Al（OC（CF ₃）₃）₄ ] ^-和[B（C ₆ F ₅）₃（OAc ^F）] ^-表现出超过或至少与常用抗衡阴离子相似的催化活性。抗衡阴离子的广泛使用在将来有关金催化中的催化剂优化方面可发挥重要作用。
