Copper-alumanyl complexes, [LCu-Al(SiN )], where L=carbene=NHC (N,N'-diisopropyl-4,5-dimethyl-2-ylidene) and CAAC (1-(2,6-diisopropylphenyl)-3,3,5,5-tetramethyl-pyrrolidin-2-ylidene) and featuring unsupported Al-Cu bonds, have been prepared. Divergent reactivity observed with carbodiimides and CO implies an ambiphilicity in the Cu-Al interaction that is dependent on the identity of the carbene co-ligand.
已经制备出铜-铝基配合物[LCu-Al(SiN )]，其中L=卡宾=NHC（N，N'-二异丙基-4，5-二甲基-2-亚基）和CAAC（1-（2，6-二异丙基苯基）-3，3，5，5-四甲基-吡咯烷-2-亚基），且具有未配位的Al-Cu键。观察到与碳二亚胺和CO的不同反应性，这意味着Cu-Al相互作用中的双亲性取决于卡宾共配体的特性。
