  Palladium(II)-Catalyzed ortho-Olefination of Arenes Applying Sulfoxides as Remote Directing Groups

  摘要：

  A novel palladium-catalyzed ortho-C(sp(2))-H olefination protocol has been developed by the use of sulfoxide as the directing group. Importantly, relatively remote coordination can be accessed to achieve the ortho olefination of benzyl, 2-arylethyl, and 3-arylpropenyl sulfoxide substrates, and the olefinated sulfoxide can be easily transformed to other functionalities.

  Synthesis of Sulfur-Bridged Polycycles via Pd-Catalyzed Dehydrogenative Cyclization

  摘要：

  A general approach to sulfur-bridged polycycles by palladium-catalyzed double C(sp(2))-H bond oxidative cyclization is presented. This protocol afforded diverse sulfur-bridged five-, six-, and seven-membered polycycles in moderate to good yields with a tolerance for a wide variety of functional groups. A sulfide-bridged six-membered pyrene-thienoacene compound was synthesized readily using this method, and excellent performance for photoluminescence quantum yield was observed.

• The Epoxidation of Carbonyl Compounds with a Benzyne-Triggered Sulfur Ylide

  An efficient method for the synthesis of epoxides from carbonyl compounds, sulfoxides, and benzyne is presented. The strategy involved an epoxidation by a sulfur ylide which is formed in situ from sulfoxide and benzyne through the S–O bond insertion and deprotonation. This one-pot reaction proceeds under mild and base-free conditions, providing a convenient way to introduce the substituted methylene

  日期：——

  An electrochemical strategy for the synthesis of unsymmetrical sulfoxides has been explored using Bunte salts and aryldiazonium tetrafluoroborates under constant current electrolysis at room temperature. In addition to being eco-safe and using mild conditions, the present protocol is free from the use of metal/oxidant, and is endowed with a broad substrate scope and good functional group tolerance
