Syntheses, characterizations, and X-ray single-crystal structures of 1,8-bis(trimethylsilylamino)naphthalene aluminum hydride and the methyl derivative

The reaction of 1,8-bis(trimethylsilylamino)naphthalene (LH(2)) (1) with nBuLi yields the dilithium compound [1,8(Me(3)SiN)(2)C(10)H(6)](Li)(2)(thf)(3) (2). Compound 1 reacts with H(3)Al center dot NMe(3) with elimination of hydrogen gas to produce [1,8-(Me(3)SiN)(2)C(10)H(6)]AlH(NMe(3)) (3), and the reaction of 2 with MeAlCl(2) leads to [1,8-(Me(3)SiN)(2)C(10)H(6)]Al(Me)thf (4). Compounds 3 and 4 are the first two aluminum mononuclear compounds to contain the 1,8-diaminonaphthalene ligand. These compounds were characterized by elemental analysis, NMR and IR spectroscopy, MS, and single-crystal X-ray structural analysis. ((c) Wiley-VCH Verlag GmbH & Co.
