Highly ruffled manganese(III) complexes of meso-tetra(tert-butyl)porphyrin
Extraordinarily ruffled acetato[5,10,15,20-tetra(tert-butyl)porphinatolmanganese(III) has been prepared. The (HNMR)-H-1 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 beta-carbon atoms.
