一般說明
乙酸酐可参与环丙基酮的Friedel-Crafts′分子内环化反应，生成四氢萘酮。据报道，其可促进多种醛与活化亚甲基化合物的Knoevenagel缩合。
乙酸酐是一种酸酐，其通常被用作胺和醇的乙酰化试剂。
應用
乙酸酐可用于以下研究：
- Lipozyme TL IM（来自嗜热单胞菌的市售固定化脂肪酶）可催化丁香油的乙酰化。
- 作为乙酰基供体，对脂肪酶催化的纳米原纤化纤维素（NFC）的乙酰化进行研究。
- N-取代吡唑啉的合成。
- 稗草（Echinochloa crus-galli）淀粉的乙酰化反应。
乙酸酐可用作合成以下物质的反应物：
- 3-乙酰氧基苯甲酸（通过与3-羟基苯甲酸反应生成）
- 6-二甲基氨基-2,3-萘二甲酸酐（制备6-二甲基氨基萘酰亚胺的前体）

The pyrazole analogues of podophyllotoxin were synthesized by the chalcone route. This route attracts the attention because of its simple operating conditions and easy availability ofthe chemicals. Initially, benzylide-neacetophenones (chalcones) were prepared in high yields by Claisen-Schmidt reaction of acetophenones
