In the present study, a heterogeneous palladium catalyst system, Pd nanoparticles supported on MRGO@CoAl-LDH, was synthesized and employed in reductive carbonylation of nitroarenes and carbonylative Suzuki coupling reactions using formic acid as CO and H2 source. The as-obtained heterogeneous catalyst was characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning
在本研究中,合成了一种多相钯催化剂体系,即负载在 MRGO@CoAl-LDH 上的 Pd 纳米颗粒,并将其用于硝基芳烃的还原羰基化和使用甲酸作为 CO 和 H 2 的羰基化 Suzuki 偶联反应来源。通过傅里叶变换红外光谱 (FTIR)、X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、能量色散 X 射线分析 (EDAX)、热重分析 (TGA) 对所获得的多相催化剂进行表征, 和振动样品磁强计 (VSM)。纳米催化剂重复使用 5 个循环,产品产率的降低可以忽略不计。所有反应均在合适且安全的条件下以高产率进行。此外,我们已成功地将甲酸用作 CO 和 H 2气体的良好且安全的替代品。
Tetraethylorthosilicate as a mild dehydrating reagent for the synthesis of N-formamides with formic acid
environmentally benign reagent. The mild conditions in this system enable the formylation of a variety of amino acid derivatives including stereochemically labile phenylglycine ethyl ester with 96% ee. This new protocol could also be applied to simple amines including weakly basic aniline derivatives, giving various primary and secondary formamides.
