7787-70-4, Copper(I) bromide is a copper-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
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.
As the paragraph descriping shows that 7787-70-4 is playing an increasingly important role.
