There is tremendous interest in water-compatible lanthanide triflate-based catalysts for carbon-carbon bond forming reactions; however, poor understanding of their aqueous mechanism severely limits the ability to increase the utility of these catalysts. Here, we report dynamic measurements of the water-coordination number of lanthanide triflate-based catalysts using luminescence-decay measurements in a range of aqueous systems. This unique characterization method is a reliable, convenient, and fast approach to analyze lanthanide-based catalysts in aqueous systems.
人们对用于碳-碳键形成反应的水相兼容三氟甲磺酸镧系催化剂有着浓厚的兴趣;然而,对其水相反应机理的了解不足严重限制了提高这些催化剂实用性的能力。在此,我们报告了在一系列水体系中使用发光衰减测量法对三氟甲磺酸镧系催化剂的水配位数量进行的动态测量。这种独特的表征方法是一种可靠、便捷且快速的分析水体系中镧系催化剂的方法。
