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 (0.105 g, 0.592 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 mixture was stirred at ambient temperature for 8 h. The reaction mixture was concentrated to minimal volume, 10 mL of DMF, water, and solid NaCl were added, the precipitate was separated by filtration, washed with water, acetonitrile, dried, chromatographed on aluminum oxide using chloroform as an eluent, and reprecipitated from ethanol. Yield 0.026 g (0.0199 mmol), 68%. MS (m/z (Irel, %)): 1306.6 (98) [M]+; for C44H20N4Br8Cu calcd.: 1307.5. IR (nu, cm-1): 2925 s, 2853 m nu(C-H, Ph), 1680 w, 1488 m nu(C=C, Ph), 1467 w, 1444 w nu(C=N), 1366 w, 1351 w nu(C-N), 1175 m, 1145 w, 1108 w delta(C-H, Ph), 1024 s nu(C-C), 924 m, 858 m gamma(C-H, pyrrole ring), 756 m, 734 m, 695 m gamma(C-H, Ph). For C44H20N4Br8Cu anal. calcd. (%): C, 40.42; N, 4.29; H, 1.54; Br, 48.89. Found (%): C, 40.15; N, 4.16; H, 1.59; Br, 48.71.
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
