We report here the synthesis of a ferrocene-functionalized {Ti22Fc4} cluster with a 'dimer-of-clusters' topology, which represents the largest Ti-oxo cluster (TOC) modified with organometallic groups ever reported. The exact assembly path of {Ti22Fc4} can be inferred from its two substructures, {Ti11Fc2} and {Ti5Fc}, which can also be synthesized independently through subtle changes in reaction conditions. Furthermore, we used these clusters as photocatalysts, and have studied, for the first time, the photocatalytic activity of TOCs in the oxidative coupling of amines.
我们在此报告了一种具有“簇二聚体”拓扑结构的二茂铁功能化{Ti22Fc4}簇的合成，它代表了迄今报道的用有机金属基团修饰的最大的钛氧簇（TOC）。{Ti22Fc4}的确切组装路径可从其两个子结构{Ti11Fc2}和{Ti5Fc}推断得出，这两个子结构也可通过反应条件的细微变化独立合成。此外，我们将这些簇用作光催化剂，并首次研究了钛氧簇在胺的氧化偶联反应中的光催化活性。
