  "id": "MLC-T-CHM-008867",
  "term": "Photoenolisation",
  "field": "Chemistry",
  "definition": "A phototautomerization in which an excited carbonyl compound abstracts a hydrogen atom from a position gamma to the carbonyl group, for example from the ortho-methyl group of o-methylbenzophenone through a six-membered transition state, to give a short-lived enol, a photoenol. The photoenol reverts to the ketone thermally unless it is trapped in Diels-Alder reactions.",
