Abstract:A new general and green synthetic protocol for the synthesis of manganese(III) metallocorroles has been developed from substituted aryl aldehydes and 5-(4-nitrophenyl)dipyrromethane using manganese salt as template. This is the first report in the synthesis of corroles: the formation of direct Csingle bondC bond through metal initiation. This method allows higher working concentrations than those previously reported. The new A2B manganese(III) metallocorroles were synthesized in good yield for different applications. The single crystal X-ray structure of 10-(3,4,5-fluorophenyl)-5,15-bis(4-nitrophenyl)manganese(III) corrole is also reported and shows that manganese atom is situating atop on macrocyclic plane.
