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.
