Abstract

The current work presents the synthesis, characterization, and application of nickel-supported reduced graphene oxide (Ni/rGO) as an efficient catalyst for carbonylation reactions. In this work, Ni/rGO was successfully established as a highly effective, durable, and reusable catalyst for both carbonylative Suzuki coupling and alkoxy carbonylation processes utilizing cobalt carbonyl, Co₂(CO)₈ as a solid carbon monoxide (CO) source. Diaryl ketones and aryl alkyl esters were selectively synthesized in good to outstanding yield. Furthermore, the catalyst is easily recoverable and may be reused five times without significantly decreasing reactivity. The fresh and reused Ni/rGO catalysts were characterized using various methods, comprising XRD, XPS, FE-SEM, TEM, EDX, and TGA. The current procedure is devoid of harmful CO gas. Additionally, the use of earth-abundant and reusable nickel metal catalysts reveals the environmentally benign features of this protocol.

Ni/rGO：以 Co2(CO)8 为固体 C1 源进行羰基化铃木偶联和烷氧基羰基化反应的高效异相催化体系

本研究介绍了镍支撑的还原氧化石墨烯（Ni/rGO）作为羰基化反应高效催化剂的合成、表征和应用。在这项工作中，Ni/rGO 成功地被确立为一种高效、耐用和可重复使用的催化剂，可用于利用羰基钴 Co2(CO)8 作为固体一氧化碳（CO）源的羰基化铃木偶联和烷氧基羰基化过程。该催化剂可选择性地合成二芳基酮和芳基烷基酯，收率从高到低不等。此外，该催化剂易于回收，可重复使用五次而不会明显降低反应活性。新的和重复使用的 Ni/rGO 催化剂采用了多种方法进行表征，包括 XRD、XPS、FE-SEM、TEM、EDX 和 TGA。目前的工艺不产生有害的 CO 气体。此外，使用地球上丰富且可重复使用的镍金属催化剂也显示出该方案对环境无害的特点。
