However, for aluminium, only trinuclear complexes have previously been reported. To investigate the possibility of also developing both mono- and dinuclear aluminium complexes, the reactions of Et3Al and tris(2-hydroxyaryl)methanes have been examined under various conditions. In this work, trialuminium complex 1b was formed by disproportionation of the initially generated monomeric complex 2′ (Al/ligand
三(2-羟基芳基)甲烷配体以多种方式与主族金属和过渡金属配位。然而,对于铝,之前仅报道了三核配合物。为了研究同时开发单核和双核铝配合物的可能性,已经在各种条件下检查了 Et3Al 和三(2-羟基芳基)甲烷的反应。在这项工作中,三铝配合物 1b 是由最初生成的单体配合物 2'(Al/配体 = 1:1)与 Et3Al 歧化形成的。该反应使我们能够选择性地合成具有不同配位模式的铝配合物 1b、2、5 和 7。此外,在适当的条件下,单核配合物5b在C6D6中经历重排以产生三(芳氧基)配合物8。
