Iminium ion

{
  "id": "MLC-T-CHM-005608",
  "term": "Iminium ion",
  "field": "Chemistry",
  "definition": "A polyatomic cation with the general structure R2C=N+R'2, characterized by a double bond between a carbon atom and a positively charged nitrogen atom. These ions are intermediates in many organic reactions, including the Mannich reaction and the Vilsmeier-Haack reaction. In mass spectrometry, iminium ions are common fragment ions formed from the cleavage of amines, amides, and other nitrogen-containing compounds, providing structural information.",
