  Regiochemistry of the coupling of aryl radicals with nucleophiles derived from the naphthyl system. Experimental and theoretical studies

  摘要：

  We here report the photostimulated reaction of unactivated aromatic halides with ambident nucleophiles derived from the naphthyl system such as 1- and 2-naphthylamide, 2-naphthoxide, 2-naphthalenethiolate, and 2-naphthaleneselenate ions, by the S(RN)1 mechanism of nucleophilic substitution. According to our experimental results, C-arylation in position 1 of the naphthyl moiety is the only reaction observed with 2-naphthoxide ions and it is favored over N-arylation with 1- and 2-naphthylamide ions. Heteroatom arylation is preferred over C-arylation with 2-naphthalenethiolate ions while it is the only observed reaction with 2-naphthaleneselenate ions. A theoretical study was carried out to explain the regiochemistry of the system. In competition experiments, 2-naphthalenethiolate ions proved to be 1.8 +/- 0.2 times more reactive than 2-naphthoxide ions for C-substitution toward p-anisyl radicals in liquid ammonia.

  complexes have been developed. The visible-light induced reactions can be applied for the synthesis of a series of unsymmetrical diaryl selenides employing aryl bromides, aryl iodides as well as aryl chlorides under mild reaction conditions. The scale-up was readily achieved. UV-Vis spectroscopy measurements provide insight into the reaction mechanism.

  This report describes a method for Ni‐catalyzed intramolecular decarbonylative coupling, which enables the conversion of areneselenol esters to diaryl selenides. The inexpensive and readily available catalyst can be employed under mild reaction conditions for the construction of structurally diverse diaryl selenides, including heterocyclic and natural product derivatives.

  employment of a large excess of electronically activated arenes, typically employed as a cosolvent. Despite being highly effective, these methods have their own limitations in the step economy and the deployment of an excess amount of arenes. Herein, we report the evolution of a catalytic system employing arene-limited, nondirected thioarylation of arenes and heteroarenes using a complimentary dual-ligand

  硫属化物基序作为主要部分存在于大量天然产物和复杂分子中。迄今为止，这些硫属元素基序的构建仅限于使用定向基团或使用大量过量的电子活化芳烃，通常用作助溶剂。尽管非常有效，但这些方法在步骤经济和过量芳烃的部署方面有其自身的局限性。在这里，我们报告了使用互补双配体方法对芳烃和杂芳烃进行芳烃限制、非定向硫芳基化的催化体系的演变。反应由空间和电子因素的组合控制，并且使用合适的配体能够产生与经典方法产生的互补光谱的产物。配体的组合在反应方案中仍然必不可少，理论计算表明单保护氨基酸配体通过特征 [5,6]-钯环过渡态在协同金属化去质子化 (CMD) 机制中至关重要，而吡啶部分有助于活性催化剂种类的形成和产物的释放。结合实验和计算机制的研究表明，C-H 活化步骤既是区域决定的，也是速率决定的。有趣的是，发现二苯基二硫化物底物的氧化加成不太可能，
