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.

A one-pot dehydration cross-coupling reaction between allyl alcohols and sodium sulfinates that provides sulfones in good to excellent yields is presented. Its broad substrate scope includes symmetrical asymmetrical α,α-diaryl- α-aryl-substituted allylic aryl alkyl sulfinates. For substrates, the E isomer predominates with examples of stereoselectivity. Control experiments provide basis for a proposed radical-mediated mechanism. The metal-free procedure applies cheap commercially available tetrabutylammonium tribromide as catalyst H2O solvent. Notable features this simple, efficient, weakly toxic, environmentally benign strategy include mild convenient operating conditions readily accessible starting materials.
