Abstract
The N-alkyliminoalanes [tert-C4H9NAIH]4, [tert-C4H9NAID]4, [iso-C3H7NAIH]6, [C2H5NAlH]8 and [CH3NAIH]n have been prepared and intermediates such as Al3H3(N tert-C4H9)2(N tert-NHC4H9)2 and Al8H10(NC2H5)6(NHC2H5)2 isolated. Cage structures and opened cages respectively are suggested on the basis of physical data. Halogenation of these iminoalanes by HgX2 proceeds in a complicated manner, the products depending on the mole ratio used, the size of the alkylgroup and cage. HX formation during the halogenation is indicated by the formation of [Cl2AlNHR]2. Regioselectivity was observed for partial chlorination of [C2H5NAlH]8. Pyrolysis of [RNHAIHCl]2 yields [tert-C4H9NAlCl]4 and [iso-C3H7NAlCl]4.Keywords
