Abstract

original image

The addition of alkyl radicals to alkenes is a reaction of considerable significance (polymerization of olefins). Competition experiments surprisingly show that methylmaleic anhydride (1b) reacts slower with nucleophilic alkyl radicals than the unsubstituted anhydride (1a). Hence radicals are not always stabilized by alkyl groups.
