General description
多聚甲醛又称聚甲醛。其作为外部CO源参与芳香醛和酯的合成。
Application
Paraformaldehyde can be used as a:
- Methylene building block in the Mannich reaction with primary amines and alkynes to synthesize propargyl amines.
- Hydroxymethylation reagent to synthesize homoallylic alcohols by reacting with 1,1-disubstituted allenes.
- Formylation reagent in the Ir-catalyzed N-formylation of amines to synthesize formamides.

实验方案
本协议描述了一种使用甲醛完成化学交联蛋白质的方法。除零长交联剂外，甲醛是交联跨度最短（~2-3 Å）的交联剂，因此使其成为非常可靠地检测特定蛋白质-蛋白质相互作用的理想工具。
