Abstract in another language

Dialuminoxane 6, in which both aluminum atoms are coordinated by pyridine and each is part of a 1,3-bis(trimethylsilyl)-1,3,2-diazaalumina[3]ferrocenophane unit, was isolated as a side product accompanying the synthesis of the corresponding [3]ferrocenophane with Al–H or Al–Cl functionalities. Although attempted high-yield syntheses of 6 failed, its structure could be established by 1H, 13C, and 29Si NMR spectroscopy in solution and by X-ray structural analysis in the solid state. In various experiments to obtain 6, crystalline material was isolated and identified as the desired dialuminoxane either with a linear Al–O–Al (6A) or bent Al–O–Al (6B) unit. This is the first example of a structurally characterized bis(amino)dialuminoxane.
