various structural defects, was found to be a highly efficient and cost effective carbocatalyst for the one-pot base-free synthesis of amides from aromatic aldehydes and secondary amine. The chemical and structural features of GO, as probed by FTIR, Raman, XRD and HRTEM analyses, were discussed to understand the catalytic mechanism for the synthesis of amides. The present method obviates the use of transition

A Cu-catalyzed synthesis of amides from alcohols and secondary amines using the oxygen in air as the terminal oxidant has been developed. The methodology is operationally simple requiring no high pressure equipment or handling of pure oxygen. The commercially available, nonprecious metal catalyst, Cu(phen)Cl2, in conjunction with di-tert-butyl hydrazine dicarboxylate and an inorganic base provides
利用空气中的氧气作为末端氧化剂,从醇和仲胺中Cu催化合成酰胺已得到发展。该方法操作简单,不需要高压设备或纯氧气的处理。可商购的非贵金属催化剂Cu(phen)Cl 2与二叔丁基肼二羧酸酯和无机碱一起以中等到极好的收率提供了多种苯甲酰胺。胺共轭酸的p K a和醇的电子学被证明会影响碱的选择,以实现最佳反应性。提出了一种与观察到的反应性趋势,KIE和Hammett研究相一致的机制。
Ru-catalyzed direct amidation of carboxylic acids with N-substituted formamides
The direct amidation of carboxylicacids with N-substituted formamides has been accomplished via ruthenium catalysis. In the presence of ruthenium catalyst, a versatile range of carboxylicacids and N-substituted formamides undergoes amidation reaction to produce synthetically useful amides in good yields. CO in amide product came from benzoic acid but not N-substituted formamides, and which was confirmed
