  • Synthesis of organoelement derivatives of barenes (carboranes)

    日期:1965.9
    The preparation of organoelement derivatives of barenes by alkylation (barenylation) of various mercury, silicon germanium, tin, phosphorus, arsenic and antimony halides is described. Attempts to prepare the tetrabarenyltin and tribarenylphosphine compounds failed because of steric hindrance. The increase in size of the arsenic and antimony atoms allowed the tri-substituted compounds to be prepared

    The preparation of symmetrical and mixed neobarenylmercury compounds is described. Organomercuric derivatives of neobarenes react with electrophilic reagents (e.g., hydrogen chloride, mercuric chloride, bromine) under more vigorous conditions than dialkyl- and diaryl-mercurials but more easily than barenylmercury compounds. Neobarenylmercury compounds show high thermal stability; however, methyl(methylneobarenyl)-

    A bright combination: A new type of donor–acceptor dyad, carbazolylaryl‐substituted ortho‐carboranes, which are conveniently prepared from the corresponding acetylenes and decaborane pathways, showed unique excited‐state behavior associated with electron transfer unlike the meta‐ and para‐counterparts (see picture).

    日期:1970.10
    The copolymerization of a small amount of the larger (C2B8 and C2B10) carboranes with the smaller C2B5 carborane resulted in the formation of an elastomeric SiB-1 carboranesiloxane, a polymer hitherto prepared only in crystalline form. Although the elastomeric behavior of the uncured SiB-1 copolymer decreased with time, curing stabilized the rubber by inhibiting crystallization.

  • C,C′-Bis(benzodiazaborolyl)dicarba-closo-dodecaboranes: Synthesis, structures, photophysics and electrochemistry
    作者:Lothar Weber、Jan Kahlert、Regina Brockhinke、Lena Böhling、Johannes Halama、Andreas Brockhinke、Hans-Georg Stammler、Beate Neumann、Carlo Nervi、Rachel A. Harder、Mark A. Fox

    Six new C,C′-bis(benzodiazaborolyl)dicarba-closo-dodecaboranes, 1,A-R2-1,A-C2B10H10, where R represents the group 2-(1,3-Et2-1,3,2-N2BC6H4) or 2-(1,3-Ph2-1,3,2-N2BC6H4) and A is 2, 7 or 12, were synthesized from o-, m-, and p-dicarbadodecaboranes (carboranes) by lithiation and subsequent treatment with the respective 2-bromo-1,3,2-benzodiazaboroles. UV-visible and fluorescence spectra of all carboranes display low energy charge transfer emissions. While such emissions with Stokes shifts between 17 330 and 21 290 cm−1 are typical for C,C′-bis(aryl)-ortho-carboranes, the observed low-energy emissions with Stokes shifts between 8320 and 15 170 cm−1 for the meta- and para-isomers are unusual as high-energy emissions are typical for meta- and para-dicarbadodecaboranes. Fluorescence quantum yields (ϕF) for the novel 1,7- and 1,12-bis(benzodiazaborolyl)-carboranes depend on the substituents at the nitrogen atoms of the heterocycle. Thus, the para-carborane with N-ethyl substituents 1,12-(1′,3′-Et2-1′,3′,2′-N2BC6H4)2-1,12-C2B10H10 has a ϕF value of 41% in cyclohexane solution and only of 9% in the solid state, whereas the analogous 1,12-(1′,3′-Ph2-1′,3′,2′-N2BC6H4)2-1,12-C2B10H10 shows quantum yields of 3% in cyclohexane solution and 72% in the solid state. X-ray crystallographic, computational and cyclic voltammetry studies for these carboranes are also presented.
    六种新的 C,Câ²-双(并二酰基)二卡巴-代十二硼烷 1,A-R2-1,A-C2B10H10,其中 R 代表 2-(1,3-Et2-1,3,2-N2BC6H4)或 2-(1,3-Ph2-1,3,2-N2BC6H4)基团,A 为 2、7或12,通过石化作用从邻、间和对二十二硼烷硼烷)合成,然后用相应的 2--1,3,2-并二硼烷处理。所有硼烷的紫外可见光谱和荧光光谱都显示出低能电荷转移发射。对于 C,C²-双(芳基)正硼烷来说,这种斯托克斯位移介于 17â330 和 21â290 cmâ1 之间的发射是典型的,而对于元异构体和对位异构体来说,观察到的斯托克斯位移介于 8320 和 15â170 cmâ1 之间的低能发射是不寻常的,因为元和对位二碳酸硼烷具有典型的高能发射。新型 1,7- 和 1,12- 双(并二硼烷基)硼烷的荧光量子产率(ÏF)取决于杂环原子上的取代基。因此,带有 N-乙基取代基 1,12-(1â²,3â²-Et2-1â²,3â²,2â²-N2BC6H4)2-1,12-C2B10H10 的对位硼烷环己烷溶液中的 ÏF 值为 41%,而在固态中仅为 9%、而类似的 1,12-(1â²,3â²-Ph2-1â²,3â²,2â²-N2BC6H4)2-1,12-C2B10H10 在环己烷溶液中的量子产率为 3%,在固态中为 72%。此外,还介绍了这些硼烷的 X 射线晶体学、计算和循环伏安法研究。
