Synthesis and characterization of adducts of R3M (R Me, M Al, Ga In) with 5,6-benzoquinoline: X-ray crystal structures of Me3GaBQ and ClMe2AlBQ (BQ = 5,6-benzoquinoline)
摘要:
The reaction of R(3)M and AlMe(2)Cl with 5,6-benzoquinoline (BQ) gave the Lewis acid-base adducts R(3)M-BQ [R = Me, M = Al (1), Ga (2), In (3)] and ClMe(2)Al-BQ (4). These adducts are much less air- and water-sensitive than the metal trialkyls and AlMe(2)Cl. All the compounds were characterized by elemental analyses, IR, NMR and mass spectroscopy. The X-ray crystal structures of 2 and 4 showed that gallium and aluminium atoms in the molecule were tetrahedrally coordinated.

The reaction of AlMe(3) with benzo[f]quinoline gave the Lewis acid-base adduct Me(3)Al-BQ, (BQ = benzo[f]-quinoline) (benzo[f] quinoline-N)trimethylaluminium, [Al(CH3)(3)(C13H9N)]}, with an Al-N bond length of 2.057 (2) Angstrom. This adduct is much less air and water sensitive than the trialkyl metal. The complex was found to be a discrete 1:1 molecular adduct of trimethylaluminium bonded to BQ. The compound contains a tetracoordinate Al atom with distorted tetrahedral geometry.
