7787-70-4, Copper(I) bromide is a copper-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

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, 2.1 mmol 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.
