• α-Diketone Formation Accompanied by Oxidation of Sulfur Functional Group by the Reaction of <i>o</i>-Alkynylarenesulfoxide with Iodine

  The reaction of o-alkynylarenesulfoxide with iodine was investigated in detail, revealing functionalities of the formation of alpha-diketones with sulfenyl, sulfinyl, and sulfonyl. Additives can change the ratio of products to give medium-to-excellent yields. Results show that water is taken into only sulfonyl compound and that other oxygen atoms constructed in the products are presumably derived from sulfoxide of the starting material and molecular oxygen.

  Intramolecular oxygen transfer of nitrone- and sulfoxide-alkynes was achieved using a catalytic amount of Au(I) and a stoichiometric amount of iodine. The Au(I)-catalyzed cyclization of a nitrone-terminal alkyne afforded a cyclic iminoester, while cyclization of analogous nitrone-internal alkynes yielded aldehyde enones. The I-2-mediated cyclization of nitrone-alkynes afforded iodinated gamma-lactams and the I-2-mediated internal redox of the closely related sulfoxide alkynes gave diketones functionalized with a thoiether.

  Ring cyclization: A mercury‐catalyzed cyclization reaction to provide 3‐benzoylbenzo[b]thiophenes was achieved in good yields by treatment of 2‐alkynylphenyl alkyl sulfoxides with mercury chloride and 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) in benzene heated at reflux for 24 h (see scheme).
