  摘要：

  通过Suzuki-Miyaura反应，以1-四氢萘酮为原料经过两步制备的2-溴-1-(三氟甲烷磺酰氧)萘，可得到多种1,2-二芳基萘。反应具有极佳的化学选择性，优先发生溴位取代，而三氟甲烷磺酰氧基保持未反应状态。

  acetaldehydes with alkynes has been established, which provides a new and versatile straightforward procedure for the regioselective synthesis of mono-, di-, and polysubstituted naphthalenes under mild conditions. Interestingly, the present catalytic system not only differentiates between internal and terminal alkynes but also shows unprecedented complete Me3SiOH elimination selectivity for silyl alkyne substrates

  已经建立了FeCl 3促进的芳基乙醛与炔烃的环化反应，这为温和条件下单，双和多取代的萘​​的区域选择性合成提供了一种新的通用直接方法。有趣的是，本催化体系不仅在内部炔烃和末端炔烃之间进行区分，而且对甲硅烷基炔烃底物显示出前所未有的完全的Me 3 SiOH消除选择性。此外，还首次以高收率和极好的区域选择性实现了通过萘乙乙醛与内部炔烃的反应合成一系列取代的菲。

  A Cu/Pd co-catalyzed Catellani-type ortho arylation reaction of iodoarenes with aryl diazonium salts has been developed. Aryl radicals that derived from aryl diazonium salts were regioselectively installed at ortho position of iodoarenes via palladium catalyzed C−H activation. Mechanistic studies showed that, in contrast to classical Pd0−PdII−PdIV−PdII−Pd0 catalytic cycle, this radical cascades performed

  开发了碘芳烃与芳基重氮盐的Cu/Pd 共催化 Catellani 型邻位芳基化反应。衍生自芳基重氮盐的芳基通过钯催化的 CH 活化区域选择性地安装在碘芳烃的邻位。机理研究表明，与经典的Pd 0 -Pd II -Pd IV -Pd II -Pd 0催化循环相反，这种自由基级联通过Pd 0 -Pd II -Pd III -Pd I -Pd 0 循环进行。
• Synthesis of aryl-substituted naphthalenes by chemoselective Suzuki–Miyaura reactions of bromo-trifluoromethanesulfonyloxy-naphthalenes. Influence of steric and electronic parameters

  Chemoselective Suzuki-Miyaura reactions of 2-bromo-1-(trifluoromethanesulfonyloxy)naphthalene, 1-bromo-2-(trifluoromethanesulfonyloxy) naphthalene and 2-acetyl-4-bromo-1-(trifluoromethanesulfonyloxy)naphthalene, which are all readily available from the corresponding tetralone derivatives, afforded a variety of mono- and diarylnaphthalenes. The reactions generally proceed with excellent chemoselectivity in favour of the bromide position, no matter whether the bromide is located at position 1 or 2 of the naphthalene or whether the carbon attached to the triflate group is electronically more deficient by the presence of a neighbouring acetyl group.
