The deoxygenative conversion of carbon dioxide to carbon monoxide is promoted by the aluminyl anion [Al(NONAr )]- (NONAr =[O(SiMe2 NAr)2 ]2- , Ar=2,6-iPr2 C6 H3 ). The reaction proceeds via the isolable monoalumoxane anion [Al(NONAr )(O)]- , containing a terminal aluminum-oxygen bond. This species reacts with a second equivalent of carbon dioxide to afford the carbonate [Al(NONAr )(CO3 )]- , and with nitrous oxide to generate the hyponitrite anion, [Al(NONAr )(κ2 O,O'-N2 O2 )]- .

铝介导的二氧化碳通过分离的单铝氧烷阴离子的还原。

铝氧根阴离子[Al（NONAr）]-（NONAr = [O（SiMe2 NAr）2] 2-，Ar = 2,6-iPr2 C6 H3）促进了二氧化碳向一氧化碳的脱氧转化。反应通过含有末端铝-氧键的可分离的单铝氧烷阴离子[Al（NONAr）（O）]-进行。该物质与第二当量的二氧化碳反应生成碳酸盐[Al（NONAr）（CO3）]-，与一氧化二氮生成次亚硝酸盐阴离子[Al（NONAr）（κ2O，O'-N2 O2） ]-。
