Abstract

The acidic properties of EtAlCl₂ are significantly enhanced by the addition of O₂ · O₂ interaction with EtAlCl₂ initiates the cationic polymerization of cis-2-butene, the oxidation of naphthalene to the corresponding radical cation; it also favors the complexation of the Lewis acid to the metathesis catalyst W(CO)₅PPh₃, and thus promotes the catalytic activity of this complex in metathesis reactions. It is suggested that O₂ increases the electron affinity of alkylaluminium compounds. The promoting effect of O₂ in metathesis, observed by various authors, is therefore explained on the basis of Lewis acidity.
