translate English to French: Three reactions were studied: (i) the addition of nucleophile to the radical cation of arylalkenes, (ii) cleavage of the benzylic carbon–carbon bond of the radical cation of arylalkanes; and (iii) the deprotonation of the benzylic carbon–hydrogen bond of the radical cation of arylalkanes.
On a étudié trois réactions: (i) l'addition d'un nucléophile sur le cation radical des arylalcènes; (ii) le clivage de la liaison carbone–carbone benzylique du cation radical des arylalcanes et (iii) la déprotonation de la liaison carbone–hydrogène benzylique du cation radical des arylalcanes.
