Selenium-based catalysts have recently been utilized to facilitate a variety of new organic transformations, owing their intrinsic advantages, including low cost, toxicity, stability in both air and water, strong compatibility with diverse functional groups. The difunctionalization alkenes-the process incorporating two groups onto carbon-carbon double bond-has garnered particular interest within the chemical community its significant applications synthesis. Recently, organoselenium-catalyzed alkenes has emerged as an ideal powerful route obtain high-value vicinal difunctionalized molecules. This review emphasizes recent advancements this rapidly evolving field, focusing on scope, limitations, mechanisms various reactions.

Three-component selenofunctionalization processes of olefins, diselenides and sulfonamides, water, alcohols, or acids utilizing 1-fluoropyridinium triflate (FP-OTf) as a reaction promoter are reported. Under the optimal conditions, broad range vicinally functionalized selenide derivatives was accessible with high yields excellent functional group compatibilities. Mechanistic studies revealed that FP-OTf played key role in this process.

Abstract Alkenes are valuable feedstocks in organic synthesis. Selenium or sulfur‐containing coumpounds with a neighboring functional group can be easily prepared by direct difunctionalization of alkenes via three‐component reactions. It will reduce the number steps and waste generation, form complicated molecules from simple starting materials. Herein, recent developments (2013–2022) have been summarized two categories: (1) selenylation seleniranium intermediates Se‐centered radicals; (2) thiolation more diverse mechanisms products Reactions electron‐rich arenes, alcohols, water, acids, NaN 3 , amines, KSCN, sulfamides, TMSNCS, TMSN Et N ⋅ 3HF, SOCl 2 HCl, NFSI, t BuONO, pyridinium salts, BuOOH, ArN BF 4 CO CO, O CF SO Cl, R P(O)−H, (RO) P(O)SH, P(O)OH et al discussed. We hope this review do help for future research area.

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.
