Complexes with bulky hydrotris(triazolyl)borate (Ttz) ligands, TtzCuCO, were used to probe how acids change the donor properties of Ttz ligands. (Ttz(tBu,Me))CuCO shows four distinct protonation states and a gradual increase in the CO stretch. The increased electrophilic nature of the Cu center upon protonation leads to enhanced C-H activation catalysis.
具有庞大的三(三唑基)硼氢配合物（Ttz）配体的配合物，TtzCuCO，被用于探究酸如何改变 Ttz 配体的给电子性质。(Ttz(tBu,Me))CuCO 显示出四个不同的质子化状态和 CO 伸缩的逐渐增加。Cu 中心在质子化后增加的亲电性导致增强的 C-H 活化催化。
