  "id": "MLC-T-CHM-011719",
  "term": "Sydnone imines",
  "field": "Chemistry",
  "definition": "Mesoionic compounds structurally related to sydnones, where the exocyclic oxygen atom of the sydnone ring is replaced by an imino group (=NR). These compounds exhibit unique electronic structures due to their delocalized positive and negative charges within the ring. They are often used as precursors in heterocyclic synthesis.",
