  • Transition-Metal-Free Synthesis of Unsymmetrical Diaryl Chalcogenides from Arenes and Diaryl Dichalcogenides

    A transition-metal-free synthetic method has been developed for the synthesis of unsymmetrical diaryl chalcogenides (S, Se, and Te) from diaryl dichalcogenides and arenes under oxidative conditions by using potassium persulfate at room temperature. Variously substituted arenes such as anisole, thioanisole, diphenyl ether, phenol, naphthol, di- and trimethoxy benzenes, xylene, mesitylene, N,N-dimethylaniline
    已开发出一种无过渡金属的合成方法,该方法用于在室温条件下通过使用过硫酸钾,在氧化条件下由二芳基二卤化锑和芳烃合成不对称的二芳基硫属元素化物(S,Se和Te)。各种取代的芳烃,例如苯甲醚,硫代苯甲醚,二苯醚,苯酚,萘酚,二和三甲氧基苯,二甲苯,均三甲苯,N,N-二甲基苯胺,溴取代的芳烃,萘和二芳基二卤化碳经历了碳硫族键形成反应在三氟乙酸中生成不对称的二芳基硫属元素化物。为了理解反应的机理部分,由77进行了详细的中间体原位表征通过使用二苯基二硒化物为底物进行Se NMR光谱分析。77 Se NMR研究表明,亲电子物质ArE +是由二芳基二卤化二硫化物与过硫酸盐在三氟乙酸中反应生成的。芳基硫属元素离子对芳烃的亲电攻击可能是芳基-硫属元素键形成的原因。
  • Ammonium Salt-Catalyzed Highly Practical <i>Ortho</i>-Selective Monohalogenation and Phenylselenation of Phenols: Scope and Applications

    日期:2018.5.4
    An ortho-selective ammonium chloride salt-catalyzed direct C–H monohalogenation of phenols and 1,1′-bi-2-naphthol (BINOL) with 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) as the chlorinating agent has been developed. The catalyst loading was low (down to 0.01 mol %) and the reaction conditions were very mild. A wide range of substrates including BINOLs were compatible with this catalytic protocol. Chlorinated
    以1,3-二氯-5,5-二甲基乙内酰脲(DCDMH)作为氯化剂的邻位选择性氯化铵盐催化的苯酚和1,1'-联-2-萘酚(BINOL)的直接C–H单卤化反应具有已开发。催化剂负载量低(低至0.01mol%),反应条件非常温和。包括BINOL在内的多种底物均与该催化方案兼容。氯化的BINOL是有用的合成子,用于合成范围广泛的不容易合成的不对称3-芳基BINOL。另外,相同的催化体系可以促进酚的邻位选择性硒化。

    Herein, we disclose the synthesis of diaryl selenides through an unexpected C–Se coupling between aryl benzyl selenoxides and phenols. The synthetic significance of the method is that it provides a mild, rapid, and metal-free access to organoselenides in high yields with excellent functional group tolerance. This coupling of aryl benzyl selenoxides reveals a completely new reaction possibility compared
    在这里,我们公开了通过芳基苄基亚硒酸酯和苯酚之间意外的C-Se偶联合成二芳基硒化物的方法。该方法的综合意义在于,它可提供温和,快速且无金属的有机硒化物,且具有出色的官能团耐受性。与芳基亚砜相比,芳基苄基亚硒酸酯的这种偶联揭示了全新的反应可能性。我们还通过实验研究探索了这种意外转变的反应机理,并揭示了一种特殊的Se(IV)-Se(III)-Se(II)反应途径。
  • A general and green procedure for the synthesis of organochalcogenides by CuFe<sub>2</sub>O<sub>4</sub>nanoparticle catalysed coupling of organoboronic acids and dichalcogenides in PEG-400
    作者:Debasish Kundu、Nirmalya Mukherjee、Brindaban C. Ranu
    DOI:10.1039/c2ra22415a
    日期:——
    A general and efficient procedure has been developed for the synthesis of organochalcogenides (selenides and tellurides) by a simple reaction of organoboronic acids and dichalcogenides catalysed by CuFe2O4 nanoparticles in PEG-400 without any ligand. This protocol offers the scope for access to a wide spectrum of chalcogenides including diaryl, aryl–heteroaryl, aryl–styrenyl, aryl–alkenyl, aryl–allyl, aryl–alkyl and aryl–alkynyl versions. The catalyst is magnetically separable and recyclable eight times without any loss of appreciable catalytic activity. The products are obtained in high purities after evaporation of solvent followed by filtration column chromatography.

  • Relations between 77Se NMR chemical shifts of (phenylseleno)benzenes and their molecular structures derived from nine X-ray crystal structures
    作者:Jette Oddershede、Lars Henriksen、Sine Larsen
    DOI:10.1039/b211130f
    日期:2003.3.13
    An extensive library of 77Se chemical shifts have been generated from the NMR measurements on substituted (phenylseleno)benzenes, including 33 new compounds. The variation in chemical shifts cover 265 ppm ranging from 446 to 181 ppm. Crystal structures have been determined for nine selected representatives of the substituted (phenylseleno)benzenes. The analysis of the crystal structures supported that through-space interactions between selenium and the ortho-substituent observed in the crystal structures also are likely to be present in solution. The variation in the 77Se NMR chemical shifts can be rationalised from the intramolecular interactions with the substituent in the ortho-position. Furthermore it appears that these ortho-effects are roughly additive, and that it is the actual interactions and not the resulting conformational constraints that are responsible for the variations in the 77Se NMR chemical shifts.
    从取代的(苯基硒)苯的NMR测量中生成了一幅广泛的77Se化学位移库,包括33种新化合物。化学位移的变化范围覆盖了265 ppm,从446 ppm到181 ppm不等。 已确定九个选定的取代(苯基硒)苯的晶体结构。晶体结构的分析支持了在晶体结构中观察到的硒与邻位取代基之间的空间相互作用在溶液中也可能存在。 77Se NMR化学位移的变化可以从与邻位取代基的分子内相互作用中进行合理化。此外,这些邻效应似乎是粗略可加的,实际上影响77Se NMR化学位移变化的是相互作用,而不是由此产生的构象约束。
