The highly bulky bis-pocket corrole 5,10,15-tris(2,4,6-triphenylphenyl)corrole (H3TTPPC) has been synthesized. Resonance Raman spectroscopy revealed a triply bonded Mn 0 moiety in its manganese(V)-oxo complex. Direct oxygen atom transfer from (TTPPC)Mn O to styrene was confirmed by an O-18-labeling experiment. The (TTPPC)Mn-III complex also exhibits significant shape selectivity in the catalytic epoxidation of nonconjugated dienes.
