  • MCM-41-immobilized 1,10-phenanthroline–copper(<scp>i</scp>) complex: a highly efficient and recyclable catalyst for the coupling of aryl iodides with aliphatic alcohols

    日期:——
    A heterogeneous C–O coupling reaction between aryl iodides and aliphatic alcohols was achieved in neat alcohol or toluene at 110 °C in the presence of 10 mol% of the MCM-41-immobilized 1,10-phenanthroline–copper(I) complex [MCM-41-1,10-phen–CuI] with Cs2CO3 as a base, yielding a variety of aryl alkyl ethers in good to excellent yields. The new heterogeneous copper catalyst can easily be prepared by
    在存在10 mol%的MCM-41固定的1,10-咯啉-(I)络合物的存在下,在110°C的纯醇或甲苯中,芳基化物和脂肪醇之间的异质C-O偶联反应得以实现[以Cs 2 CO 3为碱的MCM-41-1,10-phen-CuI] ,可产生各种芳基烷基醚,收率好至极佳。新的多相催化剂可以很容易地通过简单的方法由市售和廉价的试剂制备,并通过过滤反应溶液进行回收并循环至少8次而不会显着降低活性。
  • Formation of nitrophenyl ethers from polyols and nitroanisoles

    Disclosed is a novel process for effecting an ether interchange reaction by heating together in the presence of a basic catalyst, a nitroaromatic ether or thioether and an organic compound containing at least one hydroxyl or mercapto group. The novelty resides particularly in carrying out the interchange in an inert solvent while sparging the heated reactants thereby to remove at least a portion of solvent along with an evolving alcohol or thiol. The process is particularly adapted to the capping of organic polyols with nitroaromatic ether groups. The capped products are useful as inter­mediates for the preparation of high molecular weight polyamines which in turn find utility in various polymer applications.
    本发明公开了一种新工艺,在碱性催化剂存在下,将硝基芳香族醚或醚和含有至少一个羟基或巯基的有机化合物一起加热,从而进行醚互换反应。新颖之处尤其在于在惰性溶剂中进行交换反应,同时对加热的反应物进行喷射,以除去至少一部分溶剂和挥发的醇或醇。 该工艺特别适用于有机多元醇与硝基芳香族醚基团的封端。封端的产品可用作制备高分子量多胺的中间体,而高分子量多胺又可用于各种聚合物应用。
