Abstract Electro‐organic reactions are now considered as one of the most efficient and environmentally benign methodologies to synthesize highly functionalized motifs like difunctionalized unsaturated compounds from readily available substrates. Excellent regioselectivity, functional group tolerance broad range substrates main advantages electrochemical difunctionalization reactions. Alkenes alkynes accept radical or ionic derivatives which makes it vital precursors for synthesis industrially relevant biologically active molecules through difunctionalization. This review aims provide readers an excellent coverage different alkenes such 1,2‐homodifunctionalization, 1,2‐heterodifunctionalization, rearrangement, ipso ‐migration, cyclization dehydrogenative annulation

Paired electrolysis is highly valuable from the viewpoint of efficiency as well atom and energy economies. In order to optimize latter two for chemical reactions, development paired electrochemical processes necessary. When both electrodes in an cell (divided undivided) are applied working electrodes, sides (oxidation reduction) yield compounds, this ideal phenomena defined electrosynthesis. This offers opportunity reduce spent time, when compared with a single system that only used achieve product interest, while ignoring other side (anodic or cathodic). case, 200% current could be achieved during electrosynthesis using cathodic anodic provide same product. efficient green process and, therefore, beneficial preserving resources minimizing waste. However, beneficial, oxidation reduction must compatible counter losses equally ease separation purification electrode products. Greater efforts required perform more systematic rational approach optimal products under conditions. Nevertheless, new computational tools assistance matter. There considerable level adventure designing electrosynthetic accompanying opportunities design innovative powerful synthetic strategies. Herein, overview several examples electrosyntheses their advantages summarized will aid researchers develop greater understanding subject subsequently employ sustainable synthesis organic molecules.
