obtained in the reactions of chlorine derivatives of 1,4-benzo-quinone. The results are discussed in terms of a radical mechanism involving a homolytic cleavage of the AlC bond in the donor-acceptor complexformed between the reactants followed by combination of alkyl radicals and aluminium derivatives of semiquinone within a cage. The stable donor-acceptor complexes and aluminium derivative of semiquinone

Reactions of several substituted 1,4-benzoquinones with ethylaluminumdichloride in dichloromethane were studied. It was found that some quinones undergo a new radical aromatic coupling under these conditions, while others undergo a 1,6-reductive O-alkylation.
