Abstract

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