Abstract
Section titled âAbstractâThe direct use of electrochemistry for the generation of reactive intermediates can have major advantages towards conventional synthetic strategies. [1] Less or no reagent waste is generated and new reaction pathways are accessible. [2] In order to exploit the electricity driven conversions for synthetic purposes and to install unique selectivity two modern approaches will be outlined: Solvent-controlled selective dehydrogenative cross-coupling reactions: A key for this is the use of boron-doped diamond anodes and fluorinated alcohols within the electrolyte. [3] This methodology opened new pathways for innovative and scalable arylation reactions. [4] New electrode systems for the anodic and cathodic conversion to value-added organic compounds. These systems are capable to go beyond common limits in electro-organic synthesis. The working horse to identify suitable electrolytic conditions is the electrosynthetic screening approach. This strategy gives also rise to fast optimization and subsequent scale-up. [5] In particular, the second approach will deal with concepts which represent milestones originating from the Baizer process. References: [1] E.J. Horn, B.R. Rosen, P.S. Baran, ACS Cent.
