As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 7787-70-4, Copper(I) bromide. This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.7787-70-4
7787-70-4, Complex 2 was obtained by a similar method as described for 1 using copper(I) bromide (0.032 g,0.22 mmol) in place of copper(I) iodide. Colorless crystals of 2 were obtained (Yield: 0.191 g, 90.3%). 1HNMR (400 M, CDCl3) delta: 7.51-7.36 (m, 22H, m,p-Ph + H3,H4-PC6H4-), 7.33-7.27 (m, 4H, H5,H6-PC6H4-),7.12-7.00 (m, 12H, o-Ph). 13C NMR (100 M, CDCl3) delta: 147.87, 147.67, 140.24, 140.16, 134.31, 134.17, 133.45,131.80, 131.07, 130.71, 130.14, 129.90, 128.93, 128.69, 127.93, 127.26 (Ar-C). 31P NMR (240 M, CDCl3) delta:-9.70 (s). Anal. Calcd for C48H38Cu2Br2P2: C, 59.83; H, 3.97. Found: C, 59.88; H, 3.97. MS (MALDI-TOF): m/zCalcd for [M-2Br-Cu + C24H19P]+, 739.1745, found 739.1747.
The synthetic route of 7787-70-4 has been constantly updated, and we look forward to future research findings.
