一般描述

乙酸酐是一种酸酐，其通常被用作胺和醇的乙酰化试剂。
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。

应用

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）

New findings about the lipase acetylation of nanofibrillated cellulose using aceti_c anhydride as acyl donor.

Mojca Božič et al.

Carbohydrate polymers, 125, 340-351 (2015-04-11)

The acetylation efficiency of nanofibrillated cellulose (NFC) with aceti_c anhydride as acetyl donor was studied using lipase from A_spergillus niger in a mixture of dimethyl sulphoxide (DMSO) and phosphate buffer solution at ambient conditions and in supercritical carbon dioxide (scCO2).

Indium(III)-catalyzed knoevenagel condensation of aldehydes and activated methylenes using aceti_c anhydride as a promoter.

Yohei Ogiwara et al.

The Journal of organic chemistry, 80(6), 3101-3110 (2015-02-18)

The combination of a catalytic amount of InCl3 and aceti_c anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic

Acetylation of barnyardgrass starch with aceti_c anhydride under iodine catalysis.

Synthesis and pharmacological studies of new pyrazole analogues of podophyllotoxin.

B Umesha et al.

Bioorganicheskaia khimiia, 40(4), 503-512 (2015-04-23)

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
