  Several highly substituted naphthalenes 3 have been synthesized in a one-pot reaction by treatment of arenes 1 with alkynes 2 in the presence of palladium acetate and silver acetate. In this Pd-catalyzed protocol, an arene provides a benzo source for the construction of a naphthalene core through twofold aryl C-H bond activation. Reaction of triphenylphosphine with diphenylethyne (2 a) under the catalysis

  在乙酸钯和乙酸银的存在下，通过用炔烃2处理芳烃1，通过一锅法反应合成了几种高度取代的萘3。在此Pd催化的方案中，芳烃通过两次芳基CH键活化提供了苯环源，用于构建萘核。在Pd（IV）配合物的催化下，三苯膦与二苯乙炔（2 a）的反应产生1,2,3,4-四苯基萘（3 ba），产率为62％。在此，三苯基膦经历一个芳基CP键裂解和一个芳基CH键活化以用作苯并部分。分析了环加合物3 ea，3 ga和3 ac的晶体结构。扭曲的萘不仅来自过度拥挤的取代基，还来自CH（3）-pi相互作用的贡献。

  It has been established that an electron‐deficient (η5‐cyclopentadienyl)rhodium(III) [CpERhIII] complex is capable of catalyzing the decarboxylative and oxidative [2+2+2] annulation of benzoic acids with alkynes to produce substituted naphthalenes at room temperature. The appropriate choice of the additive and the solvent is crucial for this transformation. This catalyst system allowed use of oxygen

  已经确定的是缺电子（η 5 -环戊二烯基）合铑（III）的[Cp È铑III ]络合物是能够催化脱羧和氧化的[2 + 2 + 2]的苯甲酸与炔烃环以产生取代的萘在室温下。添加剂和溶剂的适当选择是用于该转化的关键。该催化剂体系允许使用氧气作为末端氧化剂，并扩大了包括芳香族和脂肪族炔烃在内的底物范围。在这种催化中，Cp E Rh III催化剂的电子不足性质将引起强烈的铑-π相互作用，从而加速脱羧以及CH键的裂解。

  been developed for the synthesis of larger condensed arenes from aromatic hydrocarbons and internal alkynes. This protocol uses readily available [CpRhI2]n as a catalyst and Cu(OAc)2 as an oxidant and proceeds smoothly through undirected double C–H activation. The addition of trifluoroacetic acid has a crucial positive impact on the reaction selectivity and the yields of the target products. In contrast
