Diazo compounds

  "id": "MLC-T-CHM-003144",
  "term": "Diazo compounds",
  "field": "Chemistry",
  "definition": "Organic compounds in which a carbon atom is doubly bonded to the first nitrogen of the diazo group, written R2C=N+=N-, with diazomethane, CH2N2, as the simplest member. The terminal nitrogen carries the negative charge, so the group is a 1,3-dipole. On heating, photolysis, or metal catalysis they lose dinitrogen to give carbenes or metal carbenoids, which is why they serve as carbene precursors.",
