  The competition between electron transfer and S(N)2 processes in the reaction between a number of radical anions of aromatic compounds such as anthracene, pyrene, (E)-stilbene, m-tolunitrile and p-tolunitrile and different substrates such as the methyl, ethyl, butyl, 2-butyl, neopentyl and I-adamantyl halides as well as methyl, ethyl, butyl and 2-butyl methanesulfonates has been investigated in N,N-dimethylformamide. By using the reaction of the radical anions with the appropriate alkyldimethylsulfonium iodide or trialkylsulfonium iodide as model for an electron transfer process the reaction mechanism could be characterized by electrochemical means in many of the cases listed. The presence of an S(N)2 component is found to be related not only to the steric requirements at the substrate but also to the magnitude of the driving force for the electron transfer process. Ln general, the higher the standard potential of the aromatic compound is or the poorer the substrate is as electron acceptor, the more important the S(N)2 mechanism becomes. An analysis of the substitution products obtained in the reaction between anthracene radical anion and the different substrates shows a considerable rise in the yield of the 9-alkyl-9,10-dihydroanthracene isomer as the magnitude of the S(N)2 component increases.

  Radicals produced via the indirect reduction of alkyl halides by aromatic radical anions are likely to couple fast with the mediator. In the presence of activated olefins or good hydrogen atom donors the fate of the alkyl radicals might be changed. In this study rate constants for the coupling reaction (2) between primary, secondary and tertiary alkyl radicals and some aromatic radical anions were measured via the competition with addition of the radical to styrene or ethyl cinnamate, or via the competition with hydrogen atom transfer from thiophenol or 2-methyl-2-propanethiol to the alkyl radical. It is shown that for all the alkyl radicals and aromatic radical anions investigated so far the rate constant for coupling is close to 1 x 10(9) M-1 s(-1).
