    铜催化有氧氧化脱氢环化构建多环芳烃
    摘要:
    铜催化苯并[]噻吩的有氧氧化脱氢环化代表了快速构建含有苯并[]噻吩基团的多环芳烃(PAH)的有效方法。然而,这仍然是一个尚未充分探索的领域。在这里,我们建立了一种新型的铜催化苯并[]噻吩有氧氧化脱氢环化,能够利用苯并[]噻吩官能团来获得多环芳烃。该方法具有温和的反应条件、高原子经济性和显着的化学选择性,可产生多种含有苯并[]噻吩基团的多环芳烃。机理实验和DFT计算表明,原位生成的苯并噻吩自由基阳离子中间体经历了分子间环化和H2O的捕获,从而完成了氧化环芳构化反应。标记实验表明,产物中的羰基氧原子来源于反应过程中产生的H2O。

    Stable Oxypyridinium Triflate (OPT) Salts for the Synthesis of Halobenzyl Ethers
    摘要:
    A collection of new oxypyridinium triflate reagents (1a-d) for the synthesis of halobenzyl ethers from alcohols under "mix-and-heat" conditions is described. The reagents are stable organic salts that can be stored indefinitely and handled without special precautions, making them attractive for general use in organic synthesis. Halobenzylation of representative alcohols occurs in good to excellent yield.

    Herein, a nickel catalysis system for desulfonylative C(sp2)–C(sp2) reductive cross-coupling reactions of aryl sulfone derivatives with a range of aryl bromides has been established to form diverse biaryl compounds. The complex Ar–Ni(II)–SO2CF3 bearing a phosphine ligand through oxidative addition of aryl sulfone to Ni(0) species was isolated and confirmed by an X-ray, which provides solid evidence

    features mild reaction conditions, high atom economy, and remarkable chemo-selectivity, delivering a diversity of PAHs containing benzo[]thiophene groups. Mechanistic experiments and DFT calculations demonstrate that the in situ generation of benzothiophenyl radical cation intermediate undergoes the intermolecular cyclization and the capture of HO to furnish the oxidative cycloaromatization reaction.
