(NON)Al-K(TMEDA) (NON = [O(SiMeNDipp)], Dipp = 2,6-PrCH), containing an Al-K bond, activates and reductively couples cabon monoxide gas to form the [CO] ligand. This oxocarbon anion is thermally isomerised in the presence of CO and TMEDA. In contrast, the dimeric potassium aluminyl [K{Al(NON)}] yields an aluminium complex containing the hitherto unknown [CO] ligand.
（非）Al-K（TMEDA）（NON = [O(SiMeNDipp)]，Dipp = 2,6-PrCH₂）含有Al-K键，能活化一氧化碳气体并将其还原偶联形成[CO]配体。这种碳氧化合物阴离子在CO和TMEDA存在下会发生热异构化。相比之下，二聚铝钾[K{Al(NON)}]会生成一种含有迄今未知的[CO]配体的铝配合物。
