Bicycle rearrangement

{
  "id": "MLC-T-CHM-012921",
  "term": "Bicycle rearrangement",
  "field": "Chemistry",
  "definition": "A photochemical rearrangement of unsaturated molecules in which a group migrates over the perimeter of a pi system, in a motion likened to the turning of a bicycle pedal. The name describes this migration pattern, not a bicyclic structure of the substrate. It is distinct from the bicycle-pedal mechanism, a separate proposal for the photoisomerization of conjugated double bonds.",
