Abstract
The reaction of R 3M and AlMe 2Cl with 5,6-benzoquinoline (BQ) gave the Lewis acid-base adducts R 3MBQ [R Me, M Al ( 1), Ga ( 2), In ( 3) and ClMe 2AlBQ ( 4). These adducts are much less air- and water-sensitive than the metal trialkyls and AlMe 2Cl. 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.
