Description

It finds many applications in organic synthesis, as a catalyst and a reagent. It is used as a catalyst in Sandmeyer reaction for preparing aryl bromides from arylamines through diazonium salts. It forms complexes with Lewis bases, such as dimethylsulfide, which is a precursor to organocopper reagents. Reactions involving Atom Transfer Radical Polymerization (ATRP) and Cu-catalyzed Cross-Dehydrogenative Couplings (CDC) are catalyzed by CuBr complexes.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
