Sorptive insertion

  "id": "MLC-T-CHM-011063",
  "term": "Sorptive insertion",
  "field": "Chemistry",
  "definition": "A surface reaction in which a gaseous molecule inserts directly into the bond between the surface and an adsorbed species, forming a new adsorbed species, in analogy with migratory insertion of a ligand in coordination chemistry. An example is gaseous ethene reacting with a surface-bound hydrogen atom to give an adsorbed ethyl group. The same product can also arise by ethene adsorbing first and then undergoing ligand migration.",
