General description
乙酸铵（NH4CH3CO2，NH4OAc）是溶于水的吸湿性铵盐。它是环保型且价格低廉的化合物，可通过用冰醋酸与氨或碳酸铵反应来制备。它被用作催化剂以及有机合成中的氨源。
Application
乙酸铵可作为反应物和催化剂用于以下合成：
它还可以用作氮源，在Fe(III)−salen配合物作为催化剂的参与下，通过与儿茶酚和各种醛的多组分缩合反应来合成苯并噁唑衍生物。
- 通过与2-萘酚和芳香醛的三组分缩合反应制备1，3-恶嗪衍生物。
- 用芳香醛和氰基乙酸乙酯处理的对称三联吡啶衍生物。
- 通过Pd催化的邻溴芳基醛和末端炔烃的连续偶联-亚胺化-成环反应生成异喹啉、呋喃并吡啶和噻吩并吡啶。
它还可以用作氮源，在Fe(III)−salen配合物作为催化剂的参与下，通过与儿茶酚和各种醛的多组分缩合反应来合成苯并噁唑衍生物。
Features and Benefits
NH4OAc是一种环保、耐储存且安全的试剂。
