Electrochemically generated anion radicals of anthracene have been coupled in DMF with bornyl and isobornyl bromides and exo- and endo-norbornyl bromides; anion radicals of quinoxaline have been coupled with bornyl and isobornyl bromides.The exo- and endo-bromides gave in all cases nearly the same product distribution.The reaction between quinoxaline anion radical and optically active 2-bromobutane gave racemization.These results are taken as an indication that the coupling reaction between aromatic anion radicals and these sterically hindered alkyl halides involvesa dissociative electron transfer (ET) from the anion radical to the alkyl halide followed by coupling between the thus formed alkyl radical and another anion radical.
