General description
氧化镁是一种温和的碱性试剂，用于酰化、烷基化、氧化、还原、杂环的形成、叔胺的开环、芳族缩醛的硝化、氢卤化、脱卤化氢、有机汞的羰基化，并作为离去基团形成烯烃。
Application
氧化镁可作为催化剂用于：
- 正-辛烷脱氢合成辛烯。
- 芳香醛和氰乙酸乙酯的无溶剂Knoevenagel缩合反应合成亲电烯烃。
Analysis Note

In this paper, we report on the simple, reliable synthesis of polypyrrole (PPy)/graphene oxide (GO) composite nanosheets by using sacrificial-template polymerization method. Herein, MnO(2) nanoslices were chosen as a sacrificial-template to deposit PPy, which served as the oxidant as well.
