Highly Ruffled Manganese(III) Complexes of meso-Tetra(tert-butyl)porphyrin

Extraordinarily ruffled acetato[5,10,15,20-tetra(tert-butyl)porphinato]manganese(III) has been prepared. The 1H NMR spectra have revealed that the inversion barrier of the porphyrin ring exceeds 66 kJ mol−1 and that the spin densities are quite different between the diastereotopic β-carbon atoms.
