    Novel Phosphorus Cations. 3. Derivatives of the Phosphaalkyne Tetramer 1,2,5,6-Tetraphosphatricyclo[4.2.0.02,5]octadiene: Phosphonium Ions of Alkylation (EtOTf) and Acylation (MeCO+ SbCl6-), and Mono- and Diprotonation with Superacids; Synthesis of the 1-Monooxo, 1-Monothioxo, 1-Tosylimino, and 1,5-Ditosylimino Derivatives
    摘要:
    Tricyclooctadiene 5 reacts with ethyl triflate and acetyl cation hexachloroantimonate at room temperature to give the corresponding P-ethylated and P-acylated phosphonium salts 6 and 8. P-Adamantylation (with 1-AdCl/SbCl5 complex) is not chemoselective, forming 7 in a mixture. The low temperature protonation of 5 with FSO3H/SO2ClF and FSO3H/SbF5 (1:1)''magic acid''/SO2ClF gave the mono- and diphosphonium ions 9 and 10, respectively. The monooxo and monothioxo derivatives of 5 (11 and 12) were prepared by oxygenation with (TMS)(2)O-2 and sulfuration with S-8/Et(3)N, respectively. Finally the Staudinger reaction of 5 with 1 and 2 equiv of p-tosyl azide gave the mono- and 1,5-bis(p-tosylimino) derivatives 13 and 14, respectively. Multinuclear NMR data of the resulting compounds are discussed and compared.

  • Organophosphorus Compounds, 119. The Phosphaalkyne Cyclotetramer System — Syntheses, Valence Isomerizations, and Reactions

    Interestingly, these tetramers can be interconverted by various valence isomerizations. The results of thermal and photochemically-induced rearrangements are in good agreement with MO calculations carried out for the parent compounds. Phosphaalkyne cyclotetramers exhibit a highly interesting reactivity and other peculiar features. One outstanding example is the tetraphosphacubane 5, which shows unusual
    与它们的全碳类似物相反,炔环寡聚物仅在几年前才可以使用。在cyclotetramers的化学一个里程碑是tetraphosphacubane的合成和结构表征5,如叔butylphosphaacetylene(的热解产物而获得1)。从那时起,已经完成了11个环四聚体的构建,涵盖了7个不同的框架(AG)。由于使用动力学稳定的炔烃作为起始原料,所有已知的环四聚体均带有空间上需要的取代基(叔丁基,叔戊基,1-金刚烷基)。环四聚不仅可以通过1的热分解来实现,也可以通过替代和选择性途径,例如过渡属介导的,路易斯酸和碱诱导的过程,以及通过环加成至炔烃环三聚体。有趣的是,这些四聚体可通过各种化合价异构化而相互转化。热和光化学诱导的重排的结果与对母体化合物进行的MO计算非常吻合。炔环四聚物表现出高度有趣的反应性和其他特殊特征。一个杰出的例子是四环戊二烯5,由于其独特的键合排列,其显示出不同寻常的结构和光谱特性。

    While tetrahedranes as a family are scarce, neutral heteroatomic species are all but unknown, with the only reported example being AsP3 . Herein, we describe the isolation of a neutral heteroatomic X2 Y2 molecular tetrahedron (X, Y=p-block elements), which also is the long-sought-after free phosphaalkyne dimer. Di-tert-butyldiphosphatetrahedrane, (tBuCP)2 , is formed from the monomer tBuCP in a nickel-catalyzed
    尽管四面体作为一个家庭是稀缺的,但几乎不知道中性杂原子物种,唯一报道的例子是AsP3。在本文中,我们描述了中性杂原子X2 Y2分子四面体(X,Y = p嵌段元素)的分离,这也是人们长期以来追求的游离炔二聚体。使用[(NHC)Ni(CO)3](NHC = 1,3-bis(2,4,6-三甲基苯基)咪唑啉-2-亚烷基(IMes)和1,3-双(2,6-二异丙基苯基)咪唑啉-2-亚烷基(IPr))。(I)络合物的单晶X射线结构测定证实了(tBuCP)2的结构。研究了N-杂环卡宾配体对催化反应的影响,

    di‐tert‐butyldiphosphatetrahedrane (1), which is the dimer of tert‐butylphosphaalkyne. The (tBuCP)2 tetrahedron is activated selectively by Nheterocyclic carbene (NHC) nickel(I) and nickel(0) complexes, resulting in novel complexes featuring diverse (tBuCP)n‐frameworks (n=2, 4). Release of the (tBuCP)4 framework from one of the complexes was achieved by addition of CO gas. Furthermore, 1 can be used as a source for
    最早的混合磷酸盐四面体只是最近才被报道,它们的反应性实际上还没有被探索。本文中,我们对叔丁基磷酸炔烃的二聚物二叔丁基二磷酸四氢(1)进行了反应性研究。(tBuCP)2四面体被N-杂环卡宾(NHC)(I)和(0)配合物选择性激活,形成了具有多种(tBuCP)n骨架(n = 2,4)的新型配合物。(tBuCP)4骨架从其中一种配合物中释放出来是通过添加一氧化碳气体实现的。此外, 通过消除的配位域中的二叔丁基乙炔,可以将1用作P 2单元的来源。
