General description

Copper(I) bromide (CuBr) is an inorganic salt commonly used as a catalyst or a source of Cu(I) in organic synthesis.

Application

Copper(I) bromide has been used in:
  • The synthesis of tertiary alkyl amines via photoinduced copper catalysed nucelophilic substitution
  • The synthesis of complex secondary amines via photoredox-catalyzed four component click reactions
  • The synthesis of mechanophore polymers that rupture (C-C) via heterolytic, homolytic and concerted pathways
  • The intramolecular annulation of diaryl cyclic chloranes and bromanes

Features and Benefits

This high quality copper(I) bromide is tested to be extremely low in iron impurities. It is suitable for use in further copper mediated synthesis and catalysis, especially in copper mediated azide-alkyne cycloaddition click chemistry (CuAAC).
