5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II), cas is 14172-91-9, it is a common heterocyclic compound, the copper-catalyst compound, its synthesis route is as follows.,14172-91-9
(a) N-Bromosuccinimide (0.0131 g, 0.0737 mmol) was added with stirring to a solution of 0.02 g (0.0296 mol) of complex 5 in 10 mL of chloroform and the reaction mixture was heated under reflux for 5 min. The mixture was cooled, water was added, the organic layer was separated, washed with water, dried with Na2SO4, concentrated, chromatographed on aluminum oxide (using hexane, chloroform-hexane 1 : 2, and then chloroform as eluent), and reprecipitated from ethanol. Yield 0.016 g (0.0212 mmol), 72%. (b) N-Bromosuccinimide (0.00788 g, 0.0444 mmol) was added with stirring to a solution of 0.02 g (0.0296 mmol) of complex 5 in a mixture of 10 mL of chloroform and 1 mL of DMF, the reaction mixture was kept at ambient temperature for 35 min. The mixture was treated similarly to method a. Yield 0.017 g (0.0225 mmol), 76%. (c) A mixture of 0.02 g (0.0288 mmol) of porphyrin 2 and 0.052 g (0.288 mmol) of Cu(OAc)2 was dissolved in 10 mL of DMF, the reaction mixture was heated to reflux, cooled, poured into water, solid NaCl was added, the precipitate was separated by filtration, washed with water, dried, and chromatographed on aluminum oxide using chloroform as an eluent. Yield 0.02 g (0.0265 mmol), 85%. MS (m/z (Irel, %)): 754 (56) [M]+; for C44H27N4BrCu calcd.: 755. IR (nu, cm-1): 2926 s, 2855 m nu(C-H, Ph), 1790 w, 1680 w, 1488 s nu(C=C, Ph), 1457 m nu(C=N), 1366 m, 1345 s nu(C-N), 1193 s, 1169 w, 1146 m, 1072 m delta(C-H, Ph), 1005 s nu(C-C), 861 s, 796 s gamma(C-H, pyrrole ring), 749 s, 702 s, 689 m gamma(C-H, Ph). For C44H27N4BrCu anal. calcd. (%): C, 69.98; N,7.42; H, 3.60; Br, 10.58. Found (%): C, 69.72; N, 7.30; H, 3.65; Br 9.67.
With the synthetic route has been constantly updated, we look forward to future research findings about 5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II),belong copper-catalyst compound
