Abstract
The autoxidation of dimethylcadmium and of diethylzinc is inhibited by galvinoxyl and then initiated by copper salts. The inhibition is less pronounced in the autoxidation of trimethyl- and triphenyl-aluminium, and could not be observed with 1-methylheptyl- or 1-naphthyl-magnesium bromide, or butyl-lithium, probably because the organometallic compounds react rapidly with the inhibitor. It is concluded that these autoxidations proceed by a free-radical chain mechanism which does not involve a long-lived oxygen complex.Keywords
