An iridium( iii / iv / v ) redox series featuring a terminal imido complex with triplet ground state
The iridium( iii / iv / v ) imido redox series [Ir(N t Bu){N(CHCHP t Bu 2 ) 2 }] 0/+/2+ was synthesized and examined spectroscopically, magnetically, crystallographically and computationally. The monocationic iridium( iv ) imide exhibits an electronic doublet ground state with considerable ‘imidyl’...

| Zusammenfassung: | The iridium(
iii
/
iv
/
v
) imido redox series [Ir(N
t
Bu){N(CHCHP
t
Bu
2
)
2
}]
0/+/2+
was synthesized and examined spectroscopically, magnetically, crystallographically and computationally. The monocationic iridium(
iv
) imide exhibits an electronic doublet ground state with considerable ‘imidyl’ character as a result of covalent Ir–N
t
Bu bonding. Reduction gives the neutral imide [Ir(N
t
Bu){N(CHCHP
t
Bu
2
)
2
}] as the first example of an iridium complex with a triplet ground state. Its reactivity with respect to nitrene transfer to selected electrophiles (CO
2
) and nucleophiles (PMe
3
), respectively, is reported. |
