Photodeconjugation

{
  "id": "MLC-T-CHM-008840",
  "term": "Photodeconjugation",
  "field": "Chemistry",
  "definition": "A photochemical reaction where a conjugated system, such as a double bond or a carbonyl group, undergoes a rearrangement to a non-conjugated or less conjugated isomer upon light absorption. This process results in a shift of the double bond position, reducing the extent of electron delocalization. It is observed in compounds like alpha,beta-unsaturated carboxylic acids.",
