Abstract
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–H2SO4 (V/V = 3:1) is preferable with an isolated yield of 67%.
