REACTIONS OF TRIMETHYLALUMINUM WITH ALIPHATIC DIALS

The reactions of trimethylaluminium with aliphatic diols, derivatives of 1,4-butandiol and 1,3-propandiol were studied. A mixtures of linear and cyclic organoaluminium compounds were the products of these react ions carried out for AlMe(3):diol molar ratios of 3:2 or greater. One of the products isolated in all the studied reactions was a complex of a formula Me(5)Al(3)[diol(-2H)](2) possessing one central five-coordi nated aluminium atom and two terminal four-coordinated aluminium atoms . All the complexes were characterized by means of H-1, C-13 and Al-27 NMR spectra, elemental analysis and molecular weight determination.
