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.7787-70-4, Copper(I) bromide it is a common compound, a new synthetic route is introduced below.7787-70-4
General procedure: 0.022g (0.222mmol) of CuCl was added to 0.180g (0.109mmol) of [PPh4]2[1] dissolved in 20mL of MeCN solution at -35C. After stirring the resultant solution for 5min, the yellowish brown solution formed, which was filtered, and the filtrate was concentrated. A solution of Et2O (60mL) was added into the filtrate to precipitate the product at -35C. The precipitate was then washed with Et2O and dried to give [PPh4]2[3a] (0.107g, 0.058mmol, 53% based on [PPh4]2[1]). Similarly, under the same reaction conditions, using CuBr, we have isolated a yellowish brown solid of [PPh4]2[3b] (80% based on [PPh4]2[1]) upon crystallization from Et2O/MeCN.
As the paragraph descriping shows that 7787-70-4 is playing an increasingly important role.
