Abstract:

A facile demetalation of deuterohemin(DP) has been developed in a mixed solvent of acetic anhydride and hydrobromic acid. The influences of reaction time, bath temperature and the molar ratio on the yields were also investigated. Under the optimal reaction conditions for the demetalation of DP, the yield of 96.3% is obtained at the temperature of 100 ℃ for 2 h with the molar ratio of DP, hydrobromic acid and acetic anhydride about 1∶6.3∶61.2. A series of metallodeuteroporphyrins was prepared and characterized by electrospray ionization tandem mass spectrometry(ESI-MS-MS), UV-Vis and IR. In addition, we also studied the effects of different solvents on the synthesis of metalloporphyrins, and the properties of metal cations on the shift of S and Q bands of porphyrin.
