Synthesis and characterization of new dimeric aminoalanes
Abstract
The dimeric aminoalanes [Me2AlN(C6H11)2]21, (Me2AlNBui2)22, [(2,4,6-Me3C6H2)2AlNH2]24, [Cl2AlN(C6H11)2]25, (Me2AlNHCH2C5H4N-2)26 and the ammonia adduct (2,4,6-Me3C6H2)3Al·NH33 have been prepared by the reaction of substituted alanes with different amines. They have been fully characterized by elemental analyses, IR, NMR and mass spectrometry. The crystal structures of 1, 5 and 6 have been determined. Those of 1 and 6 display slightly folded four-membered rings with alternating aluminium and nitrogen atoms, while 5 consists of a square-planar Al2N2 ring system.
