A practical and efficient synthesis of N‐isobutyronitrile amides has been achieved through the direct condensation of carboxylic acid and azobisisobutyronitrile (AIBN). Carboxylic acids bearing variously substituted phenyl rings and cinnamic or phenylpropiolic acids were employed to furnish both tertiary and secondary isobutyronitrile amides in moderate to high yields. A radical pathway was proposed
通过羧酸和偶氮二异丁腈(AIBN)的直接缩合,已实现了一种实用而有效的N-异丁腈酰胺的合成方法。带有各种取代的苯环的羧酸和肉桂酸或苯丙酸被用于以中等到高产率提供叔和仲异丁腈酰胺。提出了一种自由基途径。这里介绍的方法不需要催化剂和添加剂,代表了各种实用的含有异丁腈结构单元的有价值酰胺的第一种实用方法。
