Electron-transfer ring-opening metathesis polymerization

  "id": "MLC-T-CHM-003765",
  "term": "Electron-transfer ring-opening metathesis polymerization",
  "field": "Chemistry",
  "definition": "A ring-opening metathesis polymerization that runs through one-electron redox steps, without a metal-carbene initiator. An excited photoredox catalyst or an electrode oxidizes a vinyl ether, generating a radical cation that serves as the chain carrier for ring-opening of a strained cyclic olefin. Its active chain end is a radical cation, unlike the metal carbene found in Grubbs-type systems.",
