  苯硫醚改性剂链长对 Pd 催化剂选择性乙炔部分加氢的影响

  摘要：

  我们最近报道了具有苯硫醚部分的聚合物链可以有效地修饰 Pd 催化剂表面，从而能够在富含乙烯的条件下选择性地部分氢化乙炔。在本研究中，我们合成了具有定制分子大小的低聚和聚合苯硫醚，以系统地研究有机改性剂链长的催化作用。结果表明，改性剂链长的增加有利于通过抑制乙烯的吸附和完全加氢来提高乙炔部分加氢的选择性。这归因于这样一个事实，即由于熵的原因（螯合效应），每分子具有更多硫化物基团的改性剂可以更有效地结合到 Pd 表面，从而更好地抑制乙烯吸附。相比之下，由于其更强的结合能力和小的动力学直径，乙炔对 Pd 的吸附几乎不受改性剂的存在和大小的影响。具有较大链​​长的改性剂也有利于提高催化剂的长期稳定性，因为它们具有更高的热化学稳定性和更强的抑制碳质沉积物形成的能力。目前的结果表明，与常用的有机小分子相比，聚合物可以作为更有效、更持久的选择性改性剂。具有较大链​​长的改性剂也有利于提高催化剂的长期稳定

  Aromatic polythioetheramides have repeating units represented by one or both of the following formulae and wherein X is C1-C10 divalent hydrocarbon, -0-, -S-, - SO-, - SO2- or -CO-; a is 0 or 1; Y is C,-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aralkyl, C6-C20 aryl, halogen or nitro; b, c, e and f, 0 to 4; d, 0-20 and Ar is a C6-C30 aromatic ring. Repeating units derived from C6-C30 aromatic diamines may replace up to 50 mol% of the above thioetheramide units, and from 51 to 99 mol% when Ar is isophthalyl or terephthalyl. The polymers have excellent moldability, flame retardance, heat resistance and chemical resistance, and are suitable for use as engineering plastics.

• Synthesis of molecular chains: phenylene thioether and sulfoxide oligomers
  作者：José Vicente、José A. Abad、Rosa M. López-Nicolás

  DOI：10.1016/j.tet.2008.04.108

  日期：2008.6

  The application of a general synthetic approach to prepare molecular chains is reported. It is based on a step-by-step method each consisting first in a Pd-catalyzed reaction between ArI and HXAr'Br (Ar=aryl, Ar'=arylene) to give ArXAr'Br followed by a Cu-catalyzed replacement of Br by I to give ArXAr'I that can be reacted with HXAr'Br in the following step. The application of this method is here illustrated to prepare phenylene sulfide oligomers (X=S). Starting from RC6H4I-4 (R=H, MeO, NO2, NH2) and HSC6H4BF-x (x=2, 4) it is possible to grow chains in one direction to give X(C6H4S-m)(n)C6H4R-4 (n=1, X=Br, m=4, R=H, MeO, NO2, NH2, SMe and m=2, R=H, MeO, NO2; n=1, X=I, m=2 or 4, R=H, MeO, NO2; n=2, X=Br, m=2 or 4, R=H, MeO, NO2; n=2, X=I, m=4, R=MeO, NO2; n=3, X=Br, m=4, R=MeO, NO2; n=3, X=I, m=4, R=NO2 and n=4, X=Br or I, m=4, R=NO2). From HSC6H4Br-x and IC6H4I-4 the chains can grow in two directions to give X(C6H4S-4)(n)C6H4X-4 (n=2 or 4, X=Br or I), 2-XC6H4(SC6H4-4)(n)SC6H4X-2 (n=3 or 5, X=Br). Using diiodomesitylene the dithioethers C6HMe3-2,4,6-(SC6H4X-4)(2)-1,3 (X=Br, I) have been prepared. The series of sulfoxides X(C6H4S(O)-4)(n)C6H4R-4 (X=Br, n=1, R=MeO, n=3, R=NO2, n=4, R=Br; X=R=I, n=2) has been obtained from the corresponding thioethers and PhICl2. (C) 2008 Elsevier Ltd.

• p-Phenylene sulfide oligomers and their properties. Ar–S couplings mediated by copper or by fluorine substitutions
  作者：Olivier Goyot、Marc Gingras

  日期：2009.4

  A series of monodisperse p-phenylene sulfide oligomers were efficiently synthesized by using a bidirectional growth. A strategy combining Cu-catalyzed Ar-S couplings for small oligomers and fluorine aromatic substitutions by aryl thiolates for longer ones was put forward. The latter method is Superior to Cu-catalyzed reactions for longer oligomers. Fluorine chemistry brings some new advantages Such as solubility and reactivity, Qualitative crystallinity studies were reported according to the oligomer size and the functional series, by using a microscope equipped with a heating stage and a camera.
