7787-70-4, 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. Copper(I) bromide, cas is 7787-70-4,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 2 (55mg, 0.13mmol) and Ag2O (18.5mg, 0.08mmol) in a 5mL flask was flashed with nitrogen. Anhydrous acetonitrile (1.5mL) was added and the resulting mixture was heated at 65C for 20h. CuBr2 (29.5mg, 0.13 3mmol) and K2CO3 (18.3mg, 0.13mmol) was added to the above solution. After stirring for another 20h, the mixture was filtered through Celite. The filtrate was concentrated and the residue was re-precipitated from acetonitrile/ether to give dark purple solids (240mg, 70%). IR (CHCl3) upsilon(C=O) 1595cm-1. UV-Vis (MeOH) lambdamax (epsilon): 219 (1.0¡Á104), 250 (5.2¡Á103), 340 (sh, 1.3¡Á103), 381 (sh, 5.4¡Á102) and 640 (79) nm; mueff=1.71 muB (295K); HRMS (ESI): m/z 396.1088 [M-Br]+, calcd. 396.1017.
The chemical industry reduces the impact on the environment during synthesis,7787-70-4,Copper(I) bromide,I believe this compound will play a more active role in future production and life.
