Some tips on Copper(I) bromide

7787-70-4 Copper(I) bromide 24593, acopper-catalyst compound, is more and more widely used in various fields.

As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 7787-70-4, Copper(I) bromide. This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.7787-70-4

A dry and Ar-flushed Schlenk flask was charged with P(OEt)3 (5.2 mL, 30.0 mmol) in benzene (30 mL). CuBr (4.3 g, 30.0 mmol) was added. After the mixture had stirred at r.t. for 1 h and at 80 C for 1 h, unsolved solid was removed by filtration under Ar atmosphere and solvents were evaporated from the filtrate. The resulted mixture was cooled down to -78 C and was washed with n-hexane (2*). The remained solid was dried under vacuum; this gave CuBr*P(OEt)3. Yield: 6.8 g (73%); a mixture of oil and solid.
