A common heterocyclic compound, the copper-catalyst compound, name is Copper(I) bromide,cas is 7787-70-4, mainly used in chemical industry, its synthesis route is as follows.,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 rapid development of chemical substances, we look forward to future research findings about 7787-70-4

7787-70-4, General procedure: The complexes were prepared according to the following method [14]: 1mmol of copper(I) bromide or copper(I) chloride is stirred in methanol until complete dissolution. Then, 2.1mmol of the corresponding phosphine ligand was added. The mixture was stirred at 60C for 30min. under nitrogen atmosphere. A microcrystalline precipitate was obtained by concentration of the solution at reduced pressure. The solid product was dissolved in a dichloromethane/methanol mixture and the solution was gradually cooled to 4C to give an air stable and colorless crystalline solid suitable for X-ray single-crystal diffraction studies.
