General description

Malononitrile, a weak cyanocarbon acid, is a versatile compound with exceptional reactivity. This crystalline aliphatic nitrile is used as a building block to synthesize heterocyclic compounds and polymers

Application

Malononitrile may be used in the:
  • base-promoted on-water synthesis of [1,6]-naphthyridines.†
  • synthesis of γ-ketoamides.
  • preparation of heterocyclic privileged medicinal scaffolds involving pyridine, 1,4-dihydropyridine, chromeno[2,3-b]pyridine and dihydro-1,4-dithiepine frameworks.
