The electrochemical reduction of three biphenyl halides was studied by Fourier transform faradaic admittance measurements. The results reflect competition between heterogeneous and homogeneous electron transfers and hydrogen atom abstraction in converting the halide to biphenyl. The hydrogen atom abstraction route prevails in the process when acetonitrile is the solvent and the decomposition rate of the initially formed halobiphenyl radical anions is high. The rate constant of the latter reaction for 2-bromobiphenyl in the acetonitrile system was determined to be equal to 1.5 x 104 s−1.
