Abstract A new anaerobic electrooxidative homocoupling of arylboronic acids, arylboronates and aryltrifluoroborates was developed in the presence of catalytic amounts of Pd(OAc)2 and p‐benzoquinone, which serves as a redox mediator for the oxidation of transient Pd0 to the active PdII species. The homocoupling was performed in DMF, DMF/water or in pure water. This electrochemical process avoids the use of a stoichiometric amount of chemical oxidants and subsequent formation of co‐ and by‐products.(© Wiley‐VCH Verlag GmbH & Co.
