Recent developments in electrochemical halogenation and dehalogenation reactions

Organohalides are a prevalent structural motif used as versatile building blocks to access value-added molecules, which could play a vital role in pharmaceutical applications. Newer and greener methods for their synthesis have always been of great interest as they offer unmatched applicability in various fields. Electrochemical reactions are widely recognized as a promising avenue to address the energy crisis, in particular for the development of economically viable and high-performance strategies. In this review article, we have summarised the recent developments in the field of synthetic electrochemistry towards electrochemical halogenation via various electrolytes and organohalides used as halogen sources, and electrochemical dehalogenation, including dehalogenative cross-coupling reactions and substitution reactions.
