Application
Potassium 2-methoxypyrimidin-5-yl-5-trifluoroborate can be used as a substrate in:
- Metal-free synthesis of biaryls through oxidative electrocoupling reaction.
- Cross-coupling reactions with unactivated alkyl halides in the presence of a nickel catalyst.
- Suzuki-Miyaura coupling with aryl and heteroaryl halides using a palladium catalyst.

We report herein versatile, transition metal-free and additive-free (hetero)aryl-aryl coupling reactions promoted by the oxidative electrocoupling of unsymmetrical tetra(hetero)arylborates (TABs) prepared from ligand-exchange reactions on potassium trifluoroarylborates. Exploiting the power of electrochemical oxidations, this method complements the existing organoboron toolbox.

A wide variety of bench-stable potassium heteroaryltrifluoroborates were prepared, and general reaction conditions were developed for their cross-coupling to aryl and heteroaryl halides. The cross-coupled products were obtained in good to excellent yields. This method represents an efficient and facile
