一般描述
Butyraldehyde, also known as Butanal, is an aliphatic aldehyde, that is commonly used as a versatile building block in various organic reactions, such as in the synthesis of diverse C4–C8 alcohols, esters, amines, and carboxylic acids.
应用
丁醛可用作以下反应物：
- 各种硝基芳烃衍生物的还原胺化反应合成单-N-烷基苯胺衍生物。
- 离子液体催化 Knoevenagel 与活性亚甲基化合物缩合，合成取代的亲电烯烃。
- NiCl2通过与胺和三甲基甲硅烷基氰化物反应催化合成 α-氨基腈。
