  • Photochemical Generation of Strained Cycloalkynes from Methylenecyclopropanes
    作者:Daniel P. Maurer、Rui Fan、Dasan M. Thamattoor
    DOI:10.1002/anie.201701275
    日期:2017.4.10
    anthrene and 1‐cyclobutylidene‐1a,9b‐dihydro‐1H‐cyclopropa[l]phenanthrene undergo photolysis in solution at ambient temperature to produce cyclohexyne and cyclopentyne, respectively. These strained cycloalkynes, formed via the putative cycloalkylidenecarbenes, were intercepted as Diels–Alder adducts. Calculations at the CCSD(T)/cc‐pVTZ//B3LYP/6‐31+G* level of theory show that singlet cyclopentylidenecarbene
    烃1–环亚戊基-1a,9b-二-1H-环丙烷[ l ]和1–环丁烯-1a,9b-二-1H-环丙烷[ l ]在环境温度下在溶液中发生光分解以生成环己炔和环戊炔。这些通过假定的亚环烷形成的应变炔烃被截获为狄尔斯-阿尔德加合物。在CCSD(T)/ cc-pVTZ // B3LYP / 6-31 + G *理论平上的计算表明,单重态环戊叉必须克服9.1 kcal mol -1的障碍才能重排成环己炔(使用ΔE进行环扩环) = -15.1大卡摩尔-1)。相比之下,环丁烯卡宾仅需克服1.6 kcal mol -1的势垒即可重排成环戊炔(环扩展的ΔE = -6.2 kcal mol -1)。
  • Synthesis and time resolved infrared analysis of photochemical oxiranyl carbene and diphenyl ketene precursors
    作者:Eric M. Tippmann、Ryan Curtis
    DOI:10.1016/j.tetlet.2016.08.039
    日期:2016.10
    Synthesis of a nonnitrogenous phenanthrene-based precursor of oxiranyl carbene yielded a photochemical source for diphenyl ketene after an in situ intramolecular rearrangement. The initial carbene precursor targeted rearranged from a putative spiro-oxiranyl intermediate to a cyclobutanone. Photolysis of the phenanthrene–cyclobutanone generated an infrared signal centered at 2100 cm−1 consistent with
    原位分子内重排后,合成基于的非基卡宾的前体产生了二苯乙烯酮的光化学源。最初的卡宾前体目标物从推定的螺-环氧乙烷中间体重排为环丁酮-环丁酮的光解过程产生了一个以2100 cm -1为中心的红外信号,与二苯乙烯酮的形成相一致。时间分辨红外光谱仪跟踪反应进程并测量双分子速率常数(k obs  = 9.1×10 6  M -1  s -1; 丁胺)与二乙烯酮的形成相一致。淬火实验与Stern-Volmer动力学相结合表明,自由基途径可能与基于的前体形成二苯乙烯酮有关。还讨论了重排的一般性。
  • Crystal Structure of a Cyclotetramer from a Strained Cyclic Allene
    作者:Tatenda Mahlokozera、John B. Goods、Adam M. Childs、Dasan M. Thamattoor

    The low-temperature treatment of 1,1-dibromo-1a,9b-cyclopropa[l]phenanthrene (1) with butyllithium and copper(II) chloride in THF affords a dibenzoannellated 1,2,4,6-cycloheptatetraene which undergoes a rare cyclotetramerization. The crystal structure of this “formal” 2 + 2 + 2 + 2 cyclotetramer (2) reveals a central eight-membered ring folded in a zigzag fashion with hydrogen atoms and exocyclic double

  • Polymorphism in 9-[(9<i>H</i>-Fluoren-9-ylidene)methyl]phenanthrene

    belonged to the monoclinic crystal system (space group P21/n) and displayed a twist angle of ∼75° between the phenanthrene and dibenzofulvene planes. Polymorph 5βmc, which was isolated from a later fraction, also from hexanes, was solved in the monoclinic space group P21/c and found to have a narrower interplanar angle of ∼55°. Curiously, when the synthesis of the title compound was repeated, the 5α form
