7787-70-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Copper(I) bromide, cas is 7787-70-4,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
General procedure: 0.028g (0.283mmol) of CuCl was added to 0.220g (0.133mmol) of [PPh4]2[1] dissolved in 20mL of MeCN solution. After stirring the resultant solution for 1hat RT, the yellowish brown solution formed. The solution was filtered, and the solvent was removed in vacuo. The precipitate was washed with Et2O and MeOH and extracted with CH2Cl2 which was then recrystallized with Et2O/MeOH/CH2Cl2 to give [PPh4]2[5a] (0.110g, 0.064mmol, 96% based on Se). Similarly, under the same reaction conditions, using CuBr and CuI, we have isolated a yellowish brown solid of [PPh4]2[5b] (98% based on Se) and [PPh4]2[5c] (71% based on Se), respectively, upon crystallization from Et2O/MeOH/CH2Cl2. [PPN]2[5a] and [PPN]2[5c] were synthesized according to a similar procedure.
The chemical industry reduces the impact on the environment during synthesis,7787-70-4,Copper(I) bromide,I believe this compound will play a more active role in future production and life.
