일반 설명

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

애플리케이션

Some reported applications of copper bromide are:
  • 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.

Atom transfer radical polymerization (ATRP) of methyl acrylate (MA) was carried out by continuous feeding of Cu(I) activators. Typically, the solvent, the monomer, the initiator, and the CuBr2/Me6TREN deactivator are placed in a Schlenk flask (Me6TREN: tris[2-(dimethylamino)ethyl]amine), while the CuBr/Me6TREN

ARGET ATRP: Procedure for PMMA Polymer Brush Growth

We presents an article about ARGET ATRP, and its procedure for PMMA polymer brush growth. Surface preparation before polymer brush growth consists of two steps: surface cleaning and initiator monolayer deposition.
