Proton magnetic resonance spectrometry has been used to investigate the exchange of alkyl groups between trimethylaluminium etherate and dimethylethyl-aluminium etherate in toluene in the presence of ether. The dependence of rate upon concentration of ether, total aluminium concentration, and temperature leads to the conclusion that the organoaluminium compounds undergo exchange while still complexed with ether.
