Application

Copper(I) bromide (CuBr) may be used in the synthesis of the following:
  • enantioenriched, functionalized and protected propargylamines[1]
  • polyvinylchloride bearing benzoxazine side groups[2]
  • polybutadiene having benzoxazine side-groups (PB-benzoxazine)[3]
  • mononuclear complexes [Cu(L)(PPh3)2Br][4]
  • Copper(I) bromide along with N-(n-octyl)-2-pyridylmethanimine participates in the living-radical polymerization of methyl methacrylate.[5]
