abstract

  • Reaction of N,N′-bis(mesityl)ethylenediamine with triethylaluminium in benzene leads to the formation of an aluminium diamide derivative of formula [AlEt(μ-MesNCH2CH2NMes)]n (1) (Mes = 2,4,6-Me3C6H2). Upon treatment with pyridine or THF, compound 1 is converted into dinuclear aluminium amide derivatives of general formula [AlEt(μ-MesNCH2CH2NMes)]2·2L with L = pyridine (2) and THF (3), respectively. Compounds 1, 2 and 3 have been characterized by 1H, 13C and 27Al NMR spectroscopy as well as by elemental analysis. Single crystal X-ray analysis indicates that the two adducts exist as ten-membered heterocycles with tetracoordinated aluminium centers.
