The Oxidation of Organo‐Boron Compounds Using Electrochemically Generated Peroxodicarbonate
Von Wiley-VCH zur Verfügung gestellt
Peroxodicarbonate represents a green and largely underexplored oxidizer generated electrochemically from aqueous carbonate solutions. Through state-of-the-art electrolyzer technology, highly concentrated solutions have now become accessible. These were successfully employed as green oxidizer in deborolative hydroxylations. A plethora of phenols and alcohols have thus been synthesized in up to 99% from organoboron compounds using only green and non-toxic solvents This transformation was successfully scaled-up to multi-gram batch sizes.
