Reaction Condition Screening by Using Electrochemical Microreactor: Application to Anodic Phenol-arene C,C Cross-Coupling Reaction in High Acceptor N…
2013
The anodic phenol-arene C,C cross-coupling reaction was achieved in inexpensive and sustainable media such as methanol, acetic acid, and formic acid by using an electrochemical microreactor which can provide a better performance to screen reaction conditions than in standard beaker-type electrolysis cells. Especially, formic acid as a reaction medium showed good performance. The total amount of cross-coupling product and homo-coupling products as a by-product was clearly increased as the solvent acceptor number increased. To control the selective oxidation of phenol, addition of methanol was effective.
Highly selective electrosynthesis of biphenols on graphite electrodes in fluorinated media.
2011
The direct and selective phenol coupling reaction that provides biphenols still represents a challenge in organic synthesis. The recently developed electrosynthesis on boron-doped diamond anodes with fluorinated additives was developed further to allow the application to less-expensive electrodes and fluorinated media. This advanced protocol allows the highly selective anodic phenol coupling reaction on graphite with a broad scope.
