摘要

Selective formation of 1,3,3,4.6,6-hexamethyl-1,4-diaza3,6-diinda-norborane was achieved by the reaction of bis(lithiomethyl-methylamino)methane with dimethylindium chloride by simultaneous formation of two dative metal-carbon and two metal-nitrogen bonds accompanied by two ring closures. The synthesis of heterometallic compounds of this type, namely 1,3,3,4.6,6-hexamethyl-3-alumina-1,4-diaza-6-galla-norborane [Me2AlCH2N(Me)-CH2[N(Me)CH2GaMe2], was also attempted by the reaction of his(lithiomethyl-methylamino)methane with dimethylaluminium and -gallium chloride. This compound is formed, but cannot be separated from the simultaneously formed homometallic compounds [Me2MCH2N(Me)](2)CH2, (M = Al, Ga). The compounds were identified by elemental analyses, mass spectra, NMR spectroscopy (H-1, C-13), and by determination of their crystal structures in which they are present its monomers. The norbornane-like structure is favoured over potential isomers containing three-membered rings and over polymeric aggregation in both compound. In addition, the crystal structure of dimethyl(dimethylaminomethyl)indium was determined by single crystal X-ray diffraction, which shows an intermolecular aggregation into it six-membered ring dimer.
