General description
Paraformaldehyde is also referred as polyoxymethylene. It participates as an external CO source in the synthesis of aromatic aldehydes and esters.
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.
