Sometimes the abstract says everything.
A novel preparation of aryl and heteroarylboronic acids by an
electrochemical coupling reaction is described. It is based on
the reductive coupling between aromatic or heteroaromatic
halides and a trialkyl borate. The reactions are carried out in
DMF or THF with the use of sacrificial aluminium or mag-
nesium anodes in a single-compartment cell. Arylboronic acids
are obtained with moderate to good selectivities and isolated
yields.
