  "id": "MLC-T-CHM-011315",
  "term": "Stannylidenes",
  "field": "Chemistry",
  "definition": "Reactive intermediates with the general formula R2Sn, containing a divalent tin atom bonded to two substituents and possessing two non-bonding electrons. These species are the tin analogues of carbenes and are typically highly reactive and short-lived unless stabilized by bulky substituents or coordination to a metal center. Unstabilized stannylidenes readily undergo insertion reactions or dimerization to form distannenes with a tin-tin double bond.",
