Manganese N-confused porphyrin reactivity: CH bond activation and meso carbon reductionElectronic supplementary information (ESI) available: absorption spectra for 3 and 4. See http://www.rsc.org/suppdata/cc/b3/b310522a/

Abstract

Manganese N-confused porphyrins activate C–C and C–H bonds upon heating or air oxidation; the dimer complex [Mn(NCTPP)]₂ is reduced at two meso positions, and the pyridine coordinated monomer breaks the internal C–H bond upon heating or exposure to oxygen.
