摘要
The reductive demetalation of manganese corroles was investigated in CH2Cl2/HCl （aqueous） solvent by using SnCl2 as reducing agent. It was found that the demetalation yields depend on the substituents of corrole macrocycle significantly. Electron- rich manganese corrole undergoes reductive demetalation more easily than electron-deficient ones. The isolated reductive demetalation yield of manganese 5,10,15-tris（phenyl）corrole in present system is moderate （46%）. As for electron-deficient Mn（Ⅲ） 5,10,15-tris（pentafluorophenyl）corrole, the acid-induced demetalation in HOAc-HESO4 （V/V = 3：1） is preferable with an isolated yield of 67%.
