Intermolecular carboselenenylation of easily accessible alkenes by utilizing diselenides and N-fluorobenzenesulfonimide (NFSI) under metal-free mild conditions is reported. Preliminary mechanistic studies indicate that the oxidation diselenide NFSI through a single-electron-transfer process produces an active selenenyl cationic radical species initiates intermolecular olefins, forming key Se-C C-C bonds. Under optimized conditions, broad spectrum functionally structurally diverse selenoether derivatives with promising yields accessed very high functional group tolerance.

By employing elemental selenium as the source, we have realized amidine-directed Rh(III)-catalyzed cascade C–H selenylation/[5 + 1] annulation for direct construction of structurally novel selenadiazine, benzoselenadiazine, and benzoselenazol-3-amine frameworks with specific site selectivity good functional group tolerance. Besides, obtained products can serve fundamental platforms subsequent chemical transformations, thus, feasible SeNEx reaction, SeNEx/Michael addition, simple conversion selenadiazine product into diverse other organoselenium molecules were demonstrated accordingly. Taken together, developed methodology efficiently expands space species.

Selenium-containing polymers have numerous attractive properties, such as light response behaviors, biocompatibilities, and heavy-metal-ion adhesive ability. However, the lack of efficient strategies for constructing selenium-containing limits their development. Herein, a facile but strategy is proposed synthesizing poly(sulfide selenide)s directly from elemental selenium episulfides in presence an organocatalyst system. This affords diverse with high sulfide–selenide linkage selectivity (>99%). The mechanism exploration reveals that affected by nucleophilicity organic bases: base leads to selectivity. Notably, exhibit excellent photodegradable nature. Furthermore, electrochemical properties these enable application CO2 capture. monomer compatibility this method series structures thus various thermal optical performances.

Abstract Alkynes are simple yet important organic feedstocks. The selenylation of alkynes is able to produce complex selenium‐containing compounds in a facile way. Although there some reviews about the alkynes, most them focus on one specific reaction or what types products that can be obtained. There lack attention given various uses different selenium reagents and their mechanisms. This review mainly focuses recent advances (2013–2023) based diverse reagents. Mechanisms how added work will discussed. Different types, including difunctionalization, Se‐annulation, spiro‐cyclization, C−Se coupling, click recorded this review. regioselectivity achieved through mechanisms, radicals, seleniraniums electrophilic cyclization. We hope it do help for future research area.
