    Organic and organometallic derivatives of pentaphenylbenzene, C6Ph5X: correlation of peripheral phenyl ring orientations with the steric bulk of “X”
    摘要:
    一系列的C6Ph5X化合物已通过X射线晶体学表征,其中X = H、Br、CO2H、CO2R、C[Formula: see text]CPh、cis-BrC=C(Br)Ph、2-脱氢紧邻基、和二茂铁基。此外,第一个五苯基苯的有机金属配合物已通过与六羰基铬反应制备,得到(η6-C6Ph5H)Cr(CO)3配合物,其中金属三脚架连接到邻位外环或中心环。晶体态的五苯基苯甲酸存在氢键二聚体;然而,取代基的立体体积不允许羧酸基直接连接,而是通过两个桥联甲醇分子连接。在固态中,笨重的C6Ph5X系统中外环的取向对“X”取代基的体积非常敏感,使得对位环的扭转角度随着“X”的体积增大而反向响应,从而使邻位环远离中心环的平面。这些观察结果对分子螺旋桨的相关运动以及最终对分子机器的影响进行了讨论。

  • An unusual cobalt-mediated cleavage of a hindered alkyne
    作者:Naoto Hayashi、Douglas M Ho、Robert A Pascal
    DOI:10.1016/s0040-4039(00)00667-5
    日期:2000.6
    When 1-(pentaphenylphenyl)-2-phenylacetylene (1) is heated with (η5-cyclopentadienyl)dicarbonylcobalt, 1,2,3,4-tetraphenylfluorene (3) and related minor products are formed rather than the expected tetraarylcyclobutadiene. The formation of 3 requires that a seven-carbon fragment (formally a phenylcarbyne) must be lost. Two minor products, however, result from intramolecular cyclization of the alkyne
    当1-(pentaphenylphenyl)-2-苯乙炔(1)与加热(η 5 -环戊二烯基)dicarbonylcobalt,1,2,3,4- tetraphenylfluorene(3)和相关的次要产物形成而不是预期的tetraarylcyclobutadiene。3的形成要求必须丢失7个碳原子的片段(正式名称为phenylcarbyne)。然而,两种次要产物是由炔烃的分子内环化产生的,并且这两种保留了起始原料中的所有碳。

  • Conformational subtlety in large polyphenylene molecules
    作者:Robert A Pascal、Naoto Hayashi、Douglas M Ho

    1,3-Bis(nonaphenyl-3-biphenylyl)benzene (3), a large polyphenylene molecule (C138H94), was prepared by the Diels-Alder addition of 2 equiv. of 1-(pentaphenylphenyl)-2-phenylacetylene to 1,3-bis(3-oxo-2,4,5-triphenylcyclopenta-1,4-dienyl)benzene, and its X-ray structure was determined. The experimental structures of decaphenylbiphenyl (4) and 3 were compared with calculated structures of these molecules obtained by using methods ranging from molecular mechanics to hybrid density functional theory. Surprisingly, none of the computational methods examined correctly predicted the experimentally observed conformations of both 3 and 4. (C) 2001 Elsevier Science Ltd. All rights reserved.
  • Organic and organometallic derivatives of pentaphenylbenzene, C<sub>6</sub>Ph<sub>5</sub>X: correlation of peripheral phenyl ring orientations with the steric bulk of “X”
    作者:Stacey Brydges、Brendan Gildea、John P. Grealis、Helge Müller-Bunz、Mark Stradiotto、Michael Casey、Michael J. McGlinchey

    A series of C6Ph5X compounds, including X = H, Br, CO2H, CO2R, C[Formula: see text]CPh, cis-BrC=C(Br)Ph, 2-bornenyl, and ferrocenyl, have been characterized by use of X-ray crystallography. Also, the first organometallic complexes of pentaphenylbenzene have been prepared by reaction with chromium hexacarbonyl to yield (η6-C6Ph5H)Cr(CO)3 complexes in which the metal tripod is attached either to an ortho peripheral ring or to the central ring. Crystalline pentaphenylbenzoic acid exists as a hydrogen-bonded dimer; however, the steric bulk of the substituents does not allow the carboxylic acid moieties to be linked directly but instead via two bridging methanol molecules. In the solid state, the orientation of the peripheral rings in bulky C6Ph5X systems is very sensitive to the size of the “X” substituents, such that the twist angle of the para ring responds inversely with increasing bulk of “X”, which drives the ortho rings farther out of the plane of the central ring. The relevance of these observations to correlated motion in molecular propellers, and ultimately to molecular machines, is discussed.
