Application

Copper(I) bromide (CuBr) may be used in the synthesis of the following:
  • enantioenriched, functionalized and protected propargylamines
  • polyvinylchloride bearing benzoxazine side groups
  • polybutadiene having benzoxazine side-groups (PB-benzoxazine)
  • mononuclear complexes [Cu(L)(PPh3)2Br]
  • Copper(I) bromide along with N-(n-octyl)-2-pyridylmethanimine participates in the living-radical polymerization of methyl methacrylate.
