7787-70-4, Copper(I) bromide is a copper-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Synthesis of [(SIMes)CuBr]. In an oven-dried vial, copper(I) bromide (0.522 g, 3.63 mmol), SIMes.HCl (0.86 g, 2.52 mmol) and sodium tert-butoxide (0.243 g, 2.52 mmol) were loaded inside a glovebox and stirred in dry THF (18 mL) overnight at room temperature outside of the glovebox. After filtration of the reaction mixture through a plug of Celite, the filtrate was mixed with hexane to form a precipitate. A second filtration afforded 0.808 g (71% yield) of the title complex as an off-white solid.Spectroscopic and analytical data for [(SIMes)CuBr]: 1H NMR (300 MHz, [D6]acetone): delta=7.01 (s, 4H, HAr), 4.16 (s, 4H, NCH2), 2.37 (s, 12H, ArCH3), 2.29 (s, 6H, ArCH3); 13C NMR (75 MHz, CDCl3): delta=202.6 (C, NCN), 138.5 (C, CAr), 135.3 (CH, CAr), 135.0 (C, CAr), 129.7 (CH, CAr), 51.0 (CH2, NCH2), 21.0 (CH3, ArCH3), 18.0 (CH3, ArCH3); Elemental analysis calcd for C21H26BrCuN2 (449.89): C, 56.06; H, 5.83; N, 6.23. Found: C, 55.98; H, 5.64; N, 6.21%.
