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

We developed a green method for the synthesis of spiro[4.5]trienones through an electrochemical oxidative halocyclization with N-aryl alkynamides. This reaction was conducted under metal-catalyst- and exogenous-oxidant-free conditions at room temperature. Using readily available LiCl, LiBr, LiI as halogen source, variety dearomative halo-spirocyclization products were obtained in good to excellent yields broad scope functional group tolerance.
