14172-91-9, 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. 5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II), cas is 14172-91-9,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
(a) N-Bromosuccinimide (0.026 g, 0.148 mmol) was added with stirring in four portions to a solution of 0.02 g (0.0296 mmol) of complex 5 in 10 mL of chloroform. After addition of NBS portion, 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 to minimal volume, chromatographed on aluminum oxide (using hexane, chloroform-hexane 1 : 2, and then chloroform as eluent), and reprecipitated from ethanol. Yield 0.02 g (0.0202 mmol), 69%. (b) N-Bromosuccinimide (0.0315 g, 0.177 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 stirred at ambient temperature for 3.5 h. The mixture was treated similarly to method a. Yield 0.021 g (0.0212 mmol), 72%. (c) A mixture of 0.02 g (0.0215 mmol) of porphyrin 3 and 0.038 g (0.215 mmol) of Cu(OAc)2 was dissolved in 10 mL of DMF and the reaction mixture was heated to reflux. The mixture was 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 0.018 g (0.0182 mmol), 86%. MS (m/z (Irel, %)): 991 (53) [M]+; for C44H24N4Br4Cu calcd.: 992. IR (nu, cm-1): 2925 s, 2854 m nu(C-H, Ph), 1614 w, 1489 s nu(C=C, Ph), 1466 w, 1457 m nu(C=N), 1367 m, 1351 m nu(C-N), 1193 s, 1169 m, 1145 m, 1039 m delta(C-H, Ph), 1013 m nu(C-C), 862 s, 775 m gamma(C-H, pyrrole ring), 749 m, 693 m gamma(C-H, Ph). For C44H24N4Br4Cu anal. calcd. (%): C, 53.28; N, 5.65; H, 2.44; Br, 32.22. Found (%): C, 53.02; N, 5.53; H, 2.48; Br, 32.08.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II), 14172-91-9
