An aerobic oxidation of aldehydes towards carboxylic acids in MeCN using 1 atm of pure oxygen or oxygen in air as the oxidant and a catalytic amount of single component catalyst, Fe(NO3)3·9H2O, has been developed. Carboxylic acids with different synthetically useful functional groups were obtained at room temperature. Two mechanistic pathways have been proposed based on isotopic labeling, NMR monitoring
已开发出使用1个大气压的纯氧或空气中的氧气作为氧化剂,并催化量的单组分催化剂Fe(NO 3)3 · 9H 2 O催化将MeCN中的醛类氧化为羧酸的方法。在室温下获得具有不同的合成有用的官能团的羧酸。基于同位素标记,NMR监测和对照实验,已经提出了两种机理途径。该反应的实用性已通过使用纯氧气或约30 mL / min的气流进行了数个50 mmol规模的反应来证明。
