General description

Formic acid is a simple carboxylic acid produced by the hydrolysis of methyl formate or formamide or from its salts. It is primarily used in dyeing, textile, leather, rubber, chemical, and pharmaceutical industries.

Application

Formic acid can be used as a reagent in the:
  • Co-Nx-catalyzed one-pot reductive amination of carbonyl compounds with nitro compounds to synthesize secondary amines.
  • Photoreduction of polycyclic and heterocyclic nitro arenes to corresponding amines.
  • Pd-catalyzed chemoselective hydrogenation of olefins to saturated hydrocarbons.
