for E–E bond cleavage (where E = S, Se) at room temperature and gives satisfactory yield of the titled compounds. Molecular structure of bis[p-chlorophenyl(phenyl)methyl] diselenide (3) and diphenylmethylseleno-2-propene 7 has been established with the help of single crystalX-ray analysis. The compound (3) is triclinic and crystallizes into P1¯ space group, whereas the compound 7 is monoclinic with P21/C

An efficient protocol for [2,3]-sigmatropic rearrangement of allyl and propargyl thioethers is reported. The key sulfonium ylide intermediate is in situ formed via S-arylation of arynes. This transitionmetal-freemethod allows for ready access to a wide array of functionalized thioether derivatives in good to excellent yields.
