**The presence of a negative partial charge on the benzylic carbon atom in the transition state** __(1)__ can be deduced from the experimentally determinable Hammett ϱ values. Alkyl radicals R^˙^ are accordingly seen to develop nucleophilic properties during addition to olefins. equation image
Addition of metbyl radicals to ethylene and acetylene has been studwd by nb mitio molecular-orbital calculauons In agreemen! with expcrimenlal dam, we find that, although addition IO ethylene is charactenred by a lower activation energy. addition LO acetylene is faster due to the opposile and larger
