Herein we report that the reaction of the low-valent aluminum(I) species [CpAl] (Cp = pentamethylcyclopentadienyl) with CO exhibits complete cleavages of the C═O bonds. The deoxygenating reduction reaction of [CpAl] with CO at 120 °C afforded [(Cp)AlOC(CO)] (), which featured two stacked (AlOC) units and two C═C═O ketene moieties. Moreover, the isoelectronic analogues of diimine and isothiocyanate with CO were also investigated, and the reactions of [CpAl] with Dipp-N═C═N-Dipp* and Dipp-C═N═S [Dipp* = 2,6-bis(diphenylmethyl)-4--butylphenyl; Dipp = 2,6-diisopropylphenyl] afforded dialuminylimine () and tetrameric [Cp*AlS] (), respectively.
在此我们报道，低价态铝（I）物种[CpAl]（Cp = 五甲基环戊二烯基）与CO的反应导致C═O键完全断裂。[CpAl]与CO在120°C下发生脱氧还原反应，生成[(Cp)AlOC(CO)]（），其具有两个堆叠的（AlOC）单元和两个C═C═O 乙烯酮部分。此外，还研究了二亚胺和异硫氰酸酯与CO的等电子类似物，[CpAl]与Dipp-N═C═N-Dipp和Dipp-C═N═S [Dipp = 2,6-双（二苯基甲基）-4-叔丁基苯基；Dipp = 2,6-二异丙基苯基]的反应分别生成二铝基亚胺（）和四聚体[Cp*AlS]（）。
