The roducfive demetalafion 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. Electronrich 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%.
