Retro Diels-Alder reaction

{
  "id": "MLC-T-CHM-010301",
  "term": "Retro Diels-Alder reaction",
  "field": "Chemistry",
  "definition": "A unimolecular fragmentation reaction in mass spectrometry where a cyclic molecule undergoes a reverse Diels-Alder cycloaddition, breaking into two smaller, unsaturated fragments. This reaction is often observed in the mass spectra of cyclic compounds, particularly cyclohexenes. It is a concerted pericyclic reaction that follows specific mechanistic rules.",
