N2 - Reaction of aluminium vapour or LiAlH 4 -aluminium metal-hexane with 1,4-di-t-butyl-1,4-diazabutadiene (dbdab) yields dark green [Al(dbdab) 2 ] (1), whereas AlH 3 ·NMe 3 with dbdab in hexane at -80°C yields the corresponding hydroalumination product [Al(dbdab){N(Bu t )CH 2 } 2 ] (2) as a yellow solid; although both compounds are paramagnetic, XPS (solid) and EPR (solution) spectroscopy, and X-ray structure determinations support formally Al III centres with the unpaired electron ligand-centred.
AB - Reaction of aluminium vapour or LiAlH 4 -aluminium metal-hexane with 1,4-di-t-butyl-1,4-diazabutadiene (dbdab) yields dark green [Al(dbdab) 2 ] (1), whereas AlH 3 ·NMe 3 with dbdab in hexane at -80°C yields the corresponding hydroalumination product [Al(dbdab){N(Bu t )CH 2 } 2 ] (2) as a yellow solid; although both compounds are paramagnetic, XPS (solid) and EPR (solution) spectroscopy, and X-ray structure determinations support formally Al III centres with the unpaired electron ligand-centred.
