N2 - Alumazene [(DippN)3Al3Me3] (1, Dipp = 2,6-i-Pr2C6H3) in comparison with its isoelectronic analogue C6H6 is not aromatic, its pi electrons are not delocalized, and the Al-N bonds are highly polar. 1 undergoes formal addition of silanetriols and triaminosilanes, dealkylsilylation, coordination of Lewis bases, and Me/F exchange. We prepared a dinuclear complex [(DippNH)2Al2Me2(q)2] (2) with a central Al2O2 ring and five-coordinate Al atoms in a reaction of 1 with quinolin-8-ol (Hq). The mononuclear complex [(DippNH)Al(Meq)2] (3) obtained in the reaction of 1 with 2-methyl-quinolin-8-ol (HMeq) possesses a five-coordinate Al center. The dinuclear complex 2 can be considered as a model product of alcohol addition on the formal Al-N double bond, while the mononuclear complex 3 results from subsequent reaction of remaining Al-Me moiety with a proton of HMeq. Halogenation reactions of 1 with BCl3 and BBr3 provided by Me/halogen exchange di- and trihalogenated derivatives: [(DippN)3Al3Me3-nXn] (4 : X = Cl, n = 2; 5 : X = Cl, n = 3; 6 : X = Br, n = 2; 7 : X = Br, n = 3). Prepared compounds were characterized by 1H, 13C, and 27Al NMR spectroscopy, DIP-MS analysis, and ICP OES analysis and their molecular structures were established by the single-crystal X-ray diffraction analysis.
