  "term": "Ylides",
  "field": "Chemistry",
  "definition": "Neutral dipolar species containing a negatively charged carbon atom bonded directly to a positively charged heteroatom, such as nitrogen, phosphorus, or sulfur. The formal charges are on adjacent atoms, and the carbon atom acts as a nucleophile. Phosphorus ylides are well-known reagents in the Wittig reaction for synthesizing alkenes from carbonyl compounds.",
