7787-70-4,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7787-70-4,Copper(I) bromide,as a common compound, the synthetic route is as follows.

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.

The copper(II) complexes with terpy ligand, [Cu(terpy)(ClO4)2(H2O)] (1) and [Cu(terpy)2](CF3SO3)2¡¤2H2O (2), were synthesized by modification of a previously described method for the preparation of [Cu(terpy)(H2O)](CF3SO3)2 complex [42]. The solution of 1.0mmol of terpy (233.3mg) in 2.0mL of methanol for 1 and ethanol for 2 was added slowly under stirring to the solution containing 1.0mmol of the corresponding copper(II) salt (370.5mg of Cu(ClO4)2¡¤6H2O (1) and 361.7mg of Cu(CF3SO3)2 (2)) in 5.0mL of water. The reaction mixture was stirred at room temperature for 3h. The blue crystals of 1 and 2 suitable for single-crystal X-ray analysis were grown by slow evaporation of the resulting solutions at room temperature. These crystals were filtered off and dried at ambient temperature. The yield (calculated on the basis of terpy) was 73% (375.0mg) for 1 and 78% (337.1mg) for 2.
