  The Synthesis and Transition Temperatures of Some Ortho-Dichloroterphenyls for Ferroelectric Mixtures

  摘要：

  A range of ortho-dichloroterphenyls has been prepared and evaluated for their transition temperatures and physical properties. The analogous ortho difluoro-substituted materials have been very successful as ferroelectric host materials. It was expected that the dichloro-substituted compounds would provide a greater lateral dipole and confer of dielectric biaxiality. State of the art synthetic techniques were used. For example, low-temperature ortho directed metallations provided arylboronic acids which were used in palladium-catalysed cross-coupling reactions to provide final materials. Materials with low melting points that exhibit the S-C phase have been produced.

  ortho-preferred, radical alkylation of electron-deficient (hetero)arenes is reported. A variety of electron-deficient arenes were shown to react with various primary alkyl sources, producing the alkylated (hetero)arenes in good yields. This reaction might be an alkyl radical, nucleophilic aromatic substitution reaction, rather than the traditional electrophilic Friedel–Crafts reaction. HOMO–LUMO analysis and

  报道了缺电子（杂）芳烃的非传统铁催化的，邻位优选的自由基烷基化。已显示出各种电子不足的芳烃可与各种伯烷基源反应，以高收率生产烷基化（杂）芳烃。该反应可能是烷基自由基，亲核芳香取代反应，而不是传统的亲电Friedel-Crafts反应。关于区域选择性的关键过渡态的HOMO-LUMO分析和DFT研究与观察到的反应和结论一致。

  Aromatic compounds having an alkyl group with at least 3 carbon atoms are produced in a process comprising at least one of the following steps: (1) a step of contacting a starting material that contains an aromatic compound having a branched alkyl group with at least 3 carbon atoms, with a zeolite-containing catalyst in a liquid phase in the presence of hydrogen therein, thereby changing the position of the carbon atoms of the alkyl group bonding to the aromatic ring of the compound; (2) a step of contacting a starting material that contains an aromatic compound having a branched alkyl group with at least 3 carbon atoms, with a catalyst containing zeolite and containing rhenium and/or silver, in a liquid phase, thereby changing the position of the carbon atoms of the alkyl group bonding to the aromatic ring of the compound; (3) a step of contacting a halogenated aromatic compound having an alkyl group with at least 3 carbon atoms, with an acid-type catalyst, thereby isomerizing the compound; and (4) a step of treating a mixture of isomers of an aromatic compound having an alkyl group with at least 3 carbon atoms, with a zeolite adsorbent that contains at least one exchangable cation selected from alkali metals, alkaline earth metals, lead, thallium and silver, thereby separating a specific isomer from the isomer mixture through adsorption.

  具有至少 3 个碳原子烷基的芳香族化合物的生产工艺至少包括以下一个步骤： (1) 将含有至少 3 个碳原子的支链烷基的芳香族化合物的起始原料在液相中与含沸石的催化剂在氢存在的情况下接触，从而改变烷基的碳原子与化合物的芳香环键合的位置； (2) 将含有芳香族化合物的起始原料与含沸石和含铼和/或银的催化剂在液相中接触，该芳香族化合物具有至少 3 个碳原子的支链烷基，从而改变烷基碳原子与化合物芳香环键合的位置； (3) 将具有至少 3 个碳原子的烷基的卤代芳香族化合物与酸型催化剂接触，从而使该化合物异构化；以及 (4) 用沸石吸附剂处理具有至少 3 个碳原子的烷基的芳香族化合物的异构体混合物，该沸石吸附剂含有至少一种选自碱金属、碱土金属、铅、铊和银的可交换阳离子，从而通过吸附从异构体混合物中分离出特定的异构体。

  In a method of producing an aromatic ketone an aromatic compound having an R-CH2 group ( R denotes an alkyl group, aryl group, allyl group or aralkyl group) is oxidised in liquid phase by an oxygen-containing gas in the presence of a catalyst comprising a heavy metal compound and at least one compound selected from (1) ammonia, (2) organic basic compounds and (3) onium halides while the water produced in the reaction is removed from the reaction solution. An aromatic ketone composition produced by the process comprises the aromatic ketone and 10 ppm to 3 wt% of at least one compound selected from: a benzene derivative of the formula (II) a vinylbenzene of the formula (III) a benzaldehyde of the formula (IV) where X is a substituent; n is zero or 1 to 5; R is alkyl, aryl, allyl or aralkyl and R1 is hydrogen, alkyl, aryl, allyl or aralkyl.
