  "id": "MLC-T-CHM-008758",
  "term": "Phenonium ions",
  "field": "Chemistry",
  "definition": "Carbocations in which a phenyl group participates in stabilizing the positive charge through intramolecular electrophilic aromatic substitution, forming a bridged cyclic structure. These ions are typically observed as intermediates in solvolysis reactions of certain arylalkyl compounds. The bridging phenyl group can lead to rearrangements and specific stereochemical outcomes.",
