heterobimetallic Pd–Sn catalyst for the carbonylative Suzuki coupling, aminocarbonylation reaction, and carbonylative Sonogashira coupling of aryl halides with boronic acids, amines, and aromatic alkynes leading to a three-component coupling reaction using in situ generated carbon monoxide. Under the optimized reaction conditions, a variety of bisaryl ketones, amides, and aromatic ynones have been synthesized
在此,我们报道了一种异双金属 Pd-Sn 催化剂,用于芳基卤化物与硼酸、胺和芳香炔的羰基化 Suzuki 偶联、氨基羰基化反应和羰基化 Sonogashira 偶联,从而使用原位生成的一氧化碳进行三组分偶联反应。在优化的反应条件下,以一锅法合成了多种双芳基酮、酰胺和芳香炔酮,收率中等至良好。所报道的催化剂具有较宽的反应范围和良好的官能团耐受性。
