Bis(8-quinolinolato)copper(II), cas is 10380-28-6, it is a common heterocyclic compound, the copper-catalyst compound, its synthesis route is as follows.
General procedure: To a mixture of K3PO4 (18.8 g, 88.7 mmol), CuII oxinate (780 mg,2.22 mmol), KI (3.68 g, 22.2 mmol) and 2 (10.0 g, 22.2 mmol), water(30 mL) and acetonitrile (30 mL) were added. The mixture was stirredat 120 C for 3 days. Then brine was added, and the mixture was extracted with EA. The combined organic layers were dried with anhydrous MgSO4 and concentrated under reduced pressure. The residue was purified on a silica gel column with PE:DCM (3:1) as eluent to give3 (3.27 g, 51%) as a white solid. 1H NMR (400 MHz, CDCl3): delta (ppm)7.53 (d, J=8.8 Hz, 1H), 7.39 (d, J=8.0 Hz, 1H), 7.29 (t, J=8.4 Hz,1H), 7.11 (d, J=8.0 Hz, 1H), 7.03 (s, 1H), 6.98 (t, J=7.4 Hz, 1H),6.88 (d, J=8.0 Hz, 1H), 6.34 (d, J=7.2 Hz, 1H), 6.23 (d, J=7.6 Hz,1H). 13C NMR (125 MHz, CDCl3): delta (ppm) 161.1, 160.1, 131.7, 130.5,127.7, 126.7, 125.0, 124.5, 124.0, 121.5, 114.6, 111.0, 87.7, 85.8.Anal. Calcd for C14H9BrO2 (%): C, 58.16; H, 3.14; Br, 27.64; O, 11.07;Found: C, 58.03; H, 3.02; O, 10.98.
With the rapid development of chemical substances, we look forward to future research findings about 10380-28-6
