The electrochemical behaviour of benzyl phenyl selenide was investigat
ed by voltammetry using a rotating platinum disk electrode, cyclic vol
tammetry, controlled potential coulometry and electrolysis. The measur
ements were made in acetonitrile solution. In contrast to the case of
benzyl phenyl sulfide, the oxidation products diphenyl diselenide, ben
zaldehyde and N-benzylacetamide result from the evolution of benzyl ph
enyl selenoxide and not from the corresponding initially formed radica
l cation.
