The deoxygenative conversion of carbon dioxide to carbon monoxide is promoted by the aluminyl anion [Al(NON Ar )] − (NON Ar =[O(SiMe 2 NAr) 2 ] 2− , Ar=2,6‐ i Pr 2 C 6 H 3 ). The reaction proceeds via the isolable monoalumoxane anion [Al(NON Ar )(O)] − , containing a terminal aluminum‐oxygen bond. This species reacts with a second equivalent of carbon dioxide to afford the carbonate [Al(NON Ar )(CO 3 )] − , and with nitrous oxide to generate the hyponitrite anion, [Al(NON Ar )(κ 2 O , O′ ‐N 2 O 2 )] − .
