General description

Cuprous bromide may be prepared by reduction of cupric bromide or CuSO4-NaBr.In molten state; it is grayish brown /greenish brown in color.

Application

Some applications of copper bromide reported are as a :
  • catalyst in cross coupling reactions.
  • co-catalyst in Sonogashira coupling.
  • Lewis acid in enantioselective addition of alkynes.
  • reducing agent, when complexed by three molecules of pyridine initiators for the controlled polymerization of styrene, methyl acrylate and methyl methacrylate.
Reductive homocoupling of α-bromo-α−chlorocarboxylates to dimethyl α,α′-dichlorosuccinate derivatives in presence of CuBr/LiOCH3 in methanol has been reported.

Sustained pulmonary delivery of tobramycin from microparticles composed of drug/polymer nanocomplexes offers several advantages against traditional delivery methods. Namely, in patients with cystic fibrosis, microparticle delivery can protect the tobramycin being delivered from strong mucoadhesive interactions, thus avoiding effects on...
