Pivalic anhydride is shown to be an effective reagent for direct amidation of carboxylic acids with N-alkyl anilines. The only by-product of this reaction is nontoxic pivalic acid, which can be easily removed by aqueous workup. The reactions are conducted under mild conditions and found to be compatible with a range of carboxylic acids, including aromatic, heterocyclic, acrylic, and aliphatic carboxylic
新戊酸酐被证明是一种有效的试剂,可用于羧酸与N-烷基苯胺的直接酰胺化。该反应的唯一副产物是无毒的新戊酸,可以通过水处理轻松去除。该反应在温和条件下进行,发现与一系列羧酸相容,包括芳香族、杂环、丙烯酸和脂肪族羧酸和氨基酸,可在短反应时间内生成所需的酰胺。
