REACTION OF 2-METHYL-8-QUINOLINOL WITH ALUMINUM(3) IN NONAQUEOUS MEDIA

Aluminum(lll) reacted with 2-methyl-8-quinolinol in the presence of diethylamine in chloroform solution to give hydroxy complexes of bis(2-methyl-8-quinol-inolato)aluminum(lll). When the reaction was carried out in dimethyl sulfoxide, a 1:1 adduct of tris(2-methyl-8-quinolinolato)aluminum(lll) and dimethyl sulfoxide was obtained. These compounds have been isolated in crystalline form, their stoichiometry confirmed by elemental analyses, gravimetric and titrimetric determinations, and the compounds have been characterized by single crystal X-ray diffraction data, proton nuclear magnetic resonance, infrared and mass spectra. On the basis of the available experimental evidence, probable structures for these compounds have been postulated and discussed. © 1968, American Chemical Society. All rights reserved.
