    Influence of pH and type of counterion on the formation of bismuth(III) complexes with tropolonato and 5-methyltropolonato ligands: Synthesis, structure, spectroscopic characterization and calculation studies
    摘要:
    Reactions of tropolone (Htrop) and 5-methyltropolone (5-meHtrop) with bismuth(III) triflate, perchlorate and nitrate in methanol solution at pH below 0 lead to the formation of different complexes with monomeric (Bi(5-metrop)(2)(NO3) (7)), dimeric ([Bi(trop)(2)(CF3SO3)](2) (1)) or polymeric structures ([Bi-2(trop)(4)(ClO4)(2)](n) (2), [Bi-2(trop)(4)(NO3)(2)](n) (3), [Bi-2(5-metrop)(4)(CF3SO3)(2)](n) (5) and {[Bi-2(5-metrop)(4)(ClO4) MeOH]ClO4}(n) (6)). On the other hand, if the syntheses are performed at higher pH the simple homoleptic Bi(trop) 3 (4) and Bi(5-metrop) 3 (8) compounds are obtained independently of the bismuth(III) salt used. The crystal structures of studied compounds have been determined by single-crystal X-ray diffraction. The molecular structure of 7 has been compared with its geometry received from DFT calculations giving a good correlation. The structures of 4 and 8 have been also simulated by means of the DFT method because it was not possible to obtain sufficiently large single crystals. The total coordination number of the bismuth(III) ion is six in 7, seven in 1, eight in 2, 5 and 6 and nine in 3. The optimized geometry for 4 and 8 shows a distorted triangle antiprism of oxygen atoms around metal center with three shorter and three longer Bi-O bond lengths. The compounds were characterized by FT-IR, NMR and UV-Vis techniques. IR and UV-Vis spectra of 4, 7 and 8 were also simulated by DFT methods. TD-DFT predictions demonstrate the frontier HOMOs and LUMOs cover the ligands giving LLCT character of the lowest-lying electronic transitions. NBOs analysis for these three complexes shows low p character of 5.6% (4 and 8) or 7.3% (7) for the 6s(2) lone electron pair on the bismuth(III) ion. (C) 2015 Elsevier B.V. All rights reserved.

    摘要:
    双环[1.1.0]丁烷(BCB)具有两个稠合环丙烷环,在有机合成中有着广泛的应用。它们对自由基、亲核试剂、阳离子和卡宾的多功能反应性使它们适合各种反应,包括开环和成环策略。尽管具有这种多功能性,但它们在烯反应中作为亲烯体的潜力仍未得到充分开发。考虑到这一点,并考虑到在 BCB 开环反应中实现非对映选择性的挑战,本文中,我们提出了一种独特的方法,利用 BCB 作为亲烯体,在温和的非对映选择性 Sc(OTf) 3催化的甲醛烯与硫吲哚酮/硫代内酰胺的反应中,产生 1 ,3-二取代环丁烷衍生物,产率高,区域选择性和非对映选择性优异。值得注意的是,结构不同的硫内酰胺衍生物与 BCB 进行非对映选择性加成,得到相应的环丁烷。合成的硫代吲哚取代的环丁烷可以作为后续官能团操作的通用工具。

  • Ring-Closing Synthesis of Dibenzothiophene Sulfonium Salts and Their Use as Leaving Groups for Aromatic <sup>18</sup>F-Fluorination

    Herein, we report a novel intramolecular ring-closing reaction of biaryl thioethers that give access to highly functionalized dibenzothiophene sulfonium salts under mild conditions. The resulting precursors react regioselectively with [18F]fluoride to give [18F]fluoroarenes in predictable radiochemical yields. The strategy expands the available radiochemical space and provides superior labeling efficiency

    Pd-catalyzed oxidation reactions, and they are typically used as oxidants or redox-active cocatalysts. Here, we probe the origin of a dramatic acceleration effect of Cu(OTf)2 in the C-H/C-H aerobic oxidative coupling of o-xylene. NMR spectroscopic analysis of the PdII catalyst in the presence of Cu(OTf)2, together with other experimental and DFT computational studies of the catalytic reaction, show that
    铜盐广泛用于 Pd 催化的氧化反应,它们通常用作氧化剂或氧化还原活性助催化剂。在这里,我们探讨了 Cu(OTf)2 在邻二甲苯的 CH/CH 有氧氧化偶联中显着加速效应的起源。在 Cu(OTf)2 存在下 PdII 催化剂的 NMR 光谱分析,以及催化反应的其他实验和 DFT 计算研究表明,Cu(OTf)2 通过非氧化还原途径激活 PdII 催化剂以实现 CH 活化并且对催化剂再氧化的影响可以忽略不计。这些观察导致测试其他金属三氟甲磺酸盐作为助催化剂,其结果表明 Fe(OTf)3 甚至比 Cu(OTf)2 更有效。
