Abstract

Herein, design, synthesis, and catalytic evaluation of a novel polyoxometalate-supported nanocatalyst, Pd@CuMoO₄ is reported. Using palladium at ppm levels, the catalyst demonstrated high activity in both Suzuki–Miyaura and Sonogashira–Hagihara cross-coupling reactions. It efficiently promoted CC bond formation between aryl halides and boronic acids or terminal alkynes, achieving excellent product yields. The enhanced performance was attributed to the synergistic interactions CuMoO₄ and Pd within the catalyst framework. Additionally, Pd@CuMoO₄ was recyclable for several runs in the Suzuki–Miyaura reaction with small loss of catalytic activity. The structural stability of the reused catalyst was confirmed by comprehensive analytical characterization.

Pd@CuMoO₄在suzuki-miyaura和sonogashira-hagihara偶联反应中作为增效多金属氧酸盐催化剂

本文报道了一种新型多金属氧酸盐负载纳米催化剂Pd@CuMoO₄的设计、合成和催化评价。使用ppm水平的钯，催化剂在Suzuki-Miyaura和Sonogashira-Hagihara交叉偶联反应中表现出高活性。它有效地促进了芳基卤化物与硼酸或端炔之间的CC键形成，获得了优异的产品收率。这种增强的性能归因于催化剂框架内CuMoO4和Pd的协同作用。此外，Pd@CuMoO₄在Suzuki-Miyaura反应中多次循环使用，催化活性损失很小。通过综合分析表征，证实了催化剂的结构稳定性。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
