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.
