Based on this study and previous works, the following mechanism is proposed involving a convergent paired-electrolysis process. The benzylic substrate 1 is presumably oxidized directly at the anode into radical cation C. 1e Upon elimination of a proton that could be trapped by pivaldehyde, transient benzylic radical A could be generated. On the other hand, cathodic reduction of 3a produces persistent radical anion B that could react with transient benzyl radical A to form the desired C-C bond and anionic intermediate D. The desired arylated benzylic product is obtained via aromatization through elimination of a cyanide ion which is trapped by protonated benzaldehyde to probably yield cyanohydrin 9.
