    Triphenylpyrylium salt-sensitized photoreactions of 1,4-diaryl-2,3-dioxabicyclo[2.2.2]octanes through competitive single electron-transfer pathway and proton-catalyzed pathway
    摘要:
    2,4,6-Triphenylpyrylium tetrafluoroborate (TPPBF4)-sensitized photoinduced electron-transfer (PET) reactions of 1,4-diaryl-2,3-dioxabicyclo[2.2.2]octanes 5 (a: Ar-1 = Ar-2 = p-MeOC6H4, b: Ar-1 = Ar-2 = p-MeC6H4, c: Ar-1 = Ar-2 = Ph) underwent novel fragmentation through their radical cations to give 1,4-diarylbutan-1,4-diones 6 accompanied by elimination of ethylene. On the other hand, 4-aryl-cyclohex-3-en-1-ones 7, p-substituted phenols 8, and 4-aryl-4-aryloxycyclohexanones 9 were produced through proton-catalyzed pathways when the PET reactions of 5 were performed in the absence of a certain base such as 2,6-di-tert-butylpyridine (DTBP). Particularly, the formation of 9 is consistent with the novel cationic rearrangement involving nucleophilic O-1,2-aryl shifts and C-1,4-aryl shifts. (C) 2004 Elsevier Ltd. All rights reserved.

  • Regiocontrolled synthesis of 2,4,6-triarylpyridines from methyl ketones, electron-deficient acetylenes and ammonium acetate

    A novel one-pot two-step approach for the synthesis of 2,4,6-triarylpyridines via t-BuOK/DMSO-promoted C-vinylation of a variety of methyl ketones with electron-deficient acetylenes (alkynones) followed by a cyclization of the in situ generated unsaturated 1,5-dicarbonyl species with ammonium acetate has been developed. This approach possesses competitive advantages such as high regioselectivity, available
    一种新颖的一锅两步方法,通过t -BuOK / DMSO促进的多种甲基酮的C-乙烯基与电子缺陷型乙炔(炔烃)的合成,然后环化环戊二烯,合成2,4,6-三芳基吡啶在原位用乙酸铵生成的不饱和的1,5-二羰基物种已经研制成功。该方法具有竞争优势,例如区域选择性高,可用的起始原料以及不存在过渡金属催化剂,氧化剂和不良副产物。三取代,四取代和稠合吡啶的合成证明了该开发方法的广泛合成效用。
  • Untersuchungen an diazoverbindungen und aziden—XLV

    Electrophilic diazoalkane substitution of the phosphoryl diazomethanes 2a–2e with 2,6-di-tert-butylthiapyrylium-tetrafluoroborate (1) yields the 4-(diazomethyl)-4H-thiapyranes 3a–3e; the olefin 5 is formed as by-product in all cases. The μ-allylpalladium chloride catalyzed decomposition of 3a and c leads via a 1,2-H-shift to the 4-methylen-4H-thiapyranes 6a and b; competing 1,2-C-migration, which should
    用2,6-二叔丁基硫代吡啶鎓四氟硼酸酯(1)亲电子化重氮甲烷2a - 2e的重氮烷,得到4-(重氮甲基)-4H-噻喃3a - 3e ; 在所有情况下,烯烃5都是作为副产物形成的。μ-烯丙基氯化铝催化的3a和c的分解通过1,2-H转移生成4-亚甲基-4H-噻喃6a和b;未能观察到竞争性的1,2-C迁移,该迁移应能承受thinepines 7的影响。4-亚甲基-4H-噻喃的特征是加入高氯酸(6a → 8)和4-苯基-1,2,4-三唑啉-3,5-二酮(6a,b → 9a,b)。到目前为止,在2a,3c和3a处与2,4,6-三苯基硫代吡啶鎓-高氯酸盐(10)的相应取代反应采取了一种不寻常的方式,因为形成了双(6H-吡咯烷[1,2-b]吡唑)11a - 11c而不是(重氮甲基)-4-(或2)H-噻喃基。通过11c的X射线结构分析确定了杂双环的组成。
  • A C-13 study of the reaction of 2,4,6-triarylpyrylium cations with amines
    作者:Alan R. Katritzky、Robert T.C. Brownlee、Giuseppe Musumarra
    DOI:10.1016/s0040-4020(01)83134-3
    日期:1980.1
    The reaction of primary and secondary amines with 2,4,6-triarylpyryliums is shown by C-13 NMR to proceed by fast ring opening to a vinylogous amide; in the case of primary amines this closes slowly to a pyridinium salt. The reaction in DMSO gives the pyridinium salt quantitatively when 2 moles of amines are used, with less amine significant quantities of a diketone intermediate are produced which results
    C 13 NMR表明伯和仲胺与2,4,6-三芳基吡啶的反应是通过快速开环成乙烯基酰胺进行的。在伯胺的情况下,其缓慢闭合成吡啶鎓盐。当使用2摩尔的胺时,在DMSO中的反应定量地给出吡啶鎓盐,而胺较少时,产生大量的二酮中间体,这导致转化较慢。
