Introduction

Copper(I) bromide (CuBr) is a white crystalline powder with a melting point of 504 ˚C, a boiling point of 1345 ˚C, and a specific gravity of 4.72 g/cm [³] . It is slightly soluble in cold water and decomposes in hot water, and becomes dark blue when exposed to sunlight. CuBr can be prepared by the reduction of cupric salts with sulfite in the presence of bromide, [¹] and is commercially available. It is a very useful reagent and widely used as catalyst in many organic synthetic reactions, for example in cross-dehydrogenative couplings (CDC), [²] [³] aminations, [4] Sandmeyer, [5] click [6] and multi-component reactions [7] as well as for the synthesis of a variety of types of organic compounds.
