核壳催化剂Cu_2O@HKUST-1催化性质的研究

Study on Catalytic Properties of the Cu_2O@HKUST-1 Core-shell Catalyst

过渡金属催化的碳-碳偶联反应是当前有机化学中重要的反应之一,是实现化学反应绿色化的重要基础之一。目前通过Suzuki-Type的交叉偶联反应和Ullmann-Type的自身偶联反应制备联苯化合物,常用的Pd基催化剂价格昂贵并且难以合成,相对而言核壳催化剂Cu_2O@HKUST-1有成本较低、反应条件较为温和的特点。本文通过实验验证核壳结构材料的择形优势。

Transition metal catalyzed carbon-carbon coupling reaction is one of the most important reactions in Organic Chemistry, which is the important basis to realize green chemical reaction. The preparation of biphenyl compounds by Suzuki-Type cross coupling reaction and Ullmann-Type coupling reaction. Commonly used Pd based catalysts are expensive and difficult to synthesize. Comparatively speaking, the core-shell catalyst Cu2O@HKUST-1 has the characteristics of low cost and mild reaction conditions.In this paper, the shape selectivity of core shell structure was verified by experiments.
