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.
