Dialumane 1 reacts with tBuNC to produce a reductive dimerization adduct [LAl(tBuN[double bond, length as m-dash]C-C[double bond, length as m-dash]NtBu)AlL] (2). In the presence of Na, 1 can promote linear- and cyclo-trimerization of isocyanides, affording products [Na][LAl{(tBuNC)3}AlL] (3 and 4) and [Na][LAl{(tBuNC)3}Al(C[triple bond, length as m-dash]N)L] (5), the latter of which features a unique aromatic tri(tert-butylimino)deltate dianion [C3N3(tBu)3]2-.
二铝烷1与叔丁基异腈反应生成还原二聚加合物LAl(tBuN═C—C═NtBu)AlL。在钠存在的情况下，1能促进异腈的线性三聚和环三聚，得到产物[Na]LAl{(tBuNC)3}AlL以及[Na]LAl{(tBuNC)3}Al(C≡N)L，后者具有独特的芳香族三(叔丁基亚氨基)δ二价阴离子[C3N3(tBu)3]2-。
