Abstract
The reaction of bis(lithiomethyl-methylamino)methane with di(t)butylaluminium chloride leads to the formation of 3,3,6,6-tetra-(t)butyl-1,4-dimethyl-3,6-dialumina-1,4-diaza-norbomane by simultaneous formation of two metal-carbon and two metal nitrogen bonds accompanied by two ring closure reactions. The compound was identified by an NMR analysis (H-1, C-13, Al-27) and by determination of its crystal structure. Despite the high steric demand of the (t)butyl groups, the norbornane-basket structure is favoured over potential isomers containing three-membered rings and over polymeric aggregation. The crystal structure of tri((t)butyl)aluminium has been determined. (Bu3Al)-Bu-t crystallizes as a monomer, with the molecules interconnected by weak secondary (AlC)-C-... contacts (2.95 Angstrom) leading to a slight deviation of the AlC3 units from a planar coordination geometry at the Al atoms.
