14172-91-9, 5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II) is a copper-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,14172-91-9
(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.
As the paragraph descriping shows that 14172-91-9 is playing an increasingly important role.
