Electrochemical-induced hydrofunctionalizations of alkenes and alkynes

Abstract

The hydrofunctionalizations of readily available alkenes and alkynes are one of the most effective and useful routes to afford diverse value-added compounds. Although traditional hydrofunctionalization strategies catalyzed by metal catalysts present convenient approaches, they are also accompanied by resource consumption and environmental crisis. Electrosynthesis, as a renewable and sustainable technology, has become a cost- and atom-efficient and useful synthetic route. In this review, the electrochemical-induced hydrofunctionalizations of alkenes and alkynes are summarized and presented. In each section, the electrochemical synthetic strategy to access hydrogenation and other hydrofunctionalization (hydroboration, hydrosilylation, hydroalkylation, hydroalkoxylation, hydrocyanation, hydrocarboxylation, etc.) products are elaborated in detail separately. Finally, the current challenges and prospects for electrochemical hydrofunctionalizations of unsaturated carbon‒carbon (C‒C) bonds are also discussed briefly.
