Exploiting the solvent control within electro-organic conversions is a far underestimated
parameter in prep-scale electrolysis. The beneficial application in several transformations
is outlined and in particular discussed for the dehydrogenative coupling of arenes
and heteroarenes. This simple electrolytic strategy in fluorinated solvents allows
the modulation of the substrate’s nucleophilicity and the stabilization of the intermediates
as well as of the final product from over-oxidation.
