Notes: The reactions of crotonaldehyde (CA) with ethyl aluminum chlorides have been examined using a titration technique at low temperature. The titrations were followed by 1H-NMR spectroscopy. Evidence for complexes of the type (Et2AlCl)2CA and (Et2AlCl-CA)2 has been obtained. Ethyl aluminum sesquichloride undergoes sequential addition of CA to the EtAlCl2 moiety, to the Et2AlCl moiety, and again to the EtAlCl2 moiety. Ethyl aluminum dichloride undergoes ligand redistribution, alternately disproportionating and reproportionating, the ultimate product being EtAlCl2-CA2.
