ketones, amines, hydroxylamines, and nitriles. We describe the catalytic decarboxylation of aliphatic carboxylic acids to oxime ethers. With AgNO3 as the catalyst, valuable oxime ethers bearing various substituents could be easily obtained. The broad substrate scope, easy accessibility of aliphatic carboxylic acids, and mild reaction conditions make this strategy immediately applicable to the synthesis
肟和肟醚是重要的构建基块,可以方便地转化为酮,胺,羟胺和腈。我们描述了脂肪族羧酸到肟醚的催化脱羧。用AgNO 3作为催化剂,可以容易地获得带有各种取代基的有价值的肟醚。广泛的底物范围,脂肪族羧酸的易获得性以及温和的反应条件使该策略立即适用于生物活性化合物的合成,后期功能化和修饰。实验研究表明该反应经历了一个自由基过程。
