A bulky bis-pocket manganese(V)-oxo corrole complex: observation of oxygen atom transfer between triply bonded Mn(V)[triple bond]O and alkene.
The highly bulky bis-pocket corrole 5,10,15-tris(2,4,6-triphenylphenyl)corrole (H(3)TTPPC) has been synthesized. Resonance Raman spectroscopy revealed a triply bonded Mn[triple bond]O moiety in its manganese(V)-oxo complex. Direct oxygen atom transfer from (TTPPC)Mn[triple bond]O to styrene was confirmed by an (18)O-labeling experiment. The (TTPPC)Mn(III) complex also exhibits significant shape selectivity in the catalytic epoxidation of nonconjugated dienes.
