A transition-metal-free electrochemical chalcogenative cyclization of 2-alkynyl aryl oxime with dichalcogenides has been established to assemble valuable 4-organochalcogen isoquinolines concisely. This protocol proceeds via constant electrolysis in a user-friendly undivided cell setup. It circumvents the necessity transition metal catalysts, chemical oxidants, and harsh reaction conditions. The practical utilities current were illustrated by excellent functional group tolerance, remarkable regio-selectivity, easy scalability, mild conditions, transformable isoquinoline products.

Synthesis of diversely functionalized quinoline-2-carboxylates is illustrated through electrochemical cross-dehydrogenative coupling between N-aryl glycinates and methylenecyclopropanes. An extensive range distinct functionalities well-compatible under these transition-metal- oxidant-free mild conditions, contributing to a broad substrate scope practical applicability. Cyclic voltammetric measurements control experiments suggested formal [4 + 2] cycloaddition involving radical intermediates, followed by cyclopropyl ring opening nucleophilic polar addition, consecutively fabricating C–C C–N bonds.

An electrochemical protocol for the synthesis of sulfursulfoxonium ylides and 1,3-dithioketals by reacting sulfoxonium with disulfides has been developed under simple mild conditions. By changing solubility raw materials dielectric parameters electrolyte, sulfurization enabled a selective dehydrogenation C-S construction 1,3-dithioketals. The transformation is an ideal approach to prepare organosulfur reagents broad functional group tolerance as well high selectivity, which leads vicinal difunctionalized compounds.

An efficient synthetic protocol for the selenylated cyclic isoureas was developed using electrochemical activation of diselenides. This sustainable approach permitted transition metal and chemical oxidant-free difunctionalization olefins overall access to distinct 1,2,3 triheterofunctionalized carbon skeletons. Excellent functional group tolerance noticed, allowing synthesis a series isourea derivatives. In addition, an acid-triggered skeletal isomerization facilitated urea derivatives from corresponding isoureas. Mechanistic investigations, along with voltammetric studies, enabled postulation reaction mechanism.
