  • Routes to some 3,6-disubstituted phthalonitriles and examples of phthalocyanines derived therefrom: An overview

    3-dicyanohydroquinone concerned its O -alkylation to afford 3,6-dialkoxyphthalonitriles. These are immediate precursors to near-infrared absorbing phthalocyanine derivatives. Triflation of 2,3-dicyanohydroquinone extends the scope of the compound for phthalocyanine synthesis; the bis-triflate derivative is susceptible to S N Ar reactions and readily reacts with thiols to provide 3,6-bis(alkylsulfanyl) and
    本文回顾了一些合成途径,这些途径提供了 3,6-二取代酞腈,这是合成 1,4,8,11,15,18,22,25-八取代酞菁衍生物的前体。评价了使用 Diels-Alder 反应合成 3,6-二烷基、3,6-二烷氧基甲基、3,6-二烯基和 3,6-二苯基邻苯二甲腈的早期路线。然而,审查的重点集中在 2,3-二氰基氢醌作为获得 3,6-二取代邻苯二甲腈的起始原料的范围和应用。使用 2,3-二氰基氢醌的最早例子涉及其 O-烷基化以提供 3,6-二烷氧基邻苯二甲腈。这些是近红外吸收酞菁衍生物的直接前体。2,3-二氰基氢醌的三氟甲磺酸化扩展了该化合物用于合成酞菁的范围;ñAr 反应并容易与硫醇反应生成 3,6-双(烷基硫烷基)和 3,6-双(芳基硫烷基)邻苯二甲腈。3,6-双(苯基硒基)邻苯二甲腈最近也从相同的前体中获得。从中获得的酞菁衍生物通常表现出强烈的红移 Q 波段吸收,该吸收对中心金属离子特别敏感。2
  • Novel Synthesis of 1,4-Dialkoxy-5,6,7,8-multisubstituted-2,3-dicyanonaphthalenes through Electron Transfer from Mg Metal and Efficient Development of New Naphthalocyanines
    作者:Hirofumi Maekawa、Ikuzo Nishiguchi、Takeshi Miyazaki、Aiko Harada、Yoshimasa Yamamoto

    日期:2011.4
    Novel methods for efficient synthesis of 1,4-diamyloxy-5,6,7,8-multisubstituted-2,3-dicyanonaphthalenes were successfully developed, starting from easily available 2,3-dicyanohydroquinone as a common single compound through only three steps, the first dibromination of 2,3-dicyanohydroquinone, the second Mitsunobu dialkylation of 2,3-dicyano-5,6-diboromo-1,4-hydroquinone, and the last Diels-Alder-type of cycloaddition between 1,4-alkoxy-2,3-dicyano-5,6-diboromobenzenes and multisubstituted furans, followed by reductive deoxygenation with Mg turning. The obtained 1,4-diamyloxy-5,6,7,8-multisubstituted-2,3-dicyanonaphthalenes were easily transformed into the corresponding naphthalocyanines in 20-45% yields which showed their λmax at 867-892 nm.
    成功开发了合成1,4-二氨基氧-5,6,7,8-多取代-2,3-二氰基萘的高效新方法。该方法从易得的2,3-二氰基氢醌出发,仅通过三步反应:首先是2,3-二氰基氢醌的二溴化反应,其次是2,3-二氰基-5,6-二溴-1,4-氢醌的 Mitsunobu 二烷基化反应,最后是1,4-烷氧基-2,3-二氰基-5,6-二溴苯与多取代呋喃的 Diels-Alder 型环加成反应,随后通过镁还原脱氧反应得到产物。所得的1,4-二氨基氧-5,6,7,8-多取代-2,3-二氰基萘可以轻松转化为相应的萘酞菁衍生物,产率为20-45%,其最大吸收波长在867-892 nm之间。
  • [EN] PREPARATION AND APPLICATIONS OF POLYMER-SUPPORTED HALOGENATED BENZOQUINONES AS OXIDATIVE AGENTS<br/>[FR] PREPARATION ET APPLICATIONS DE BENZOQUINONES HALOGENEES SUPPORTEES PAR POLYMERE EN TANT QU'AGENTS OXYDANTS

    This invention provides a general method for the synthesis of polymer-supported benzoquinones described by the following generic structure I: wherein: •, X, R1, R2 and R3 are described in the main text. The general concept of the method consists of the use of a halogenated starting material of the general structure II (Figure 1) which by an nucleophilic substitution reaction (NSR) or a palladium mediated coupling (PMC) is either directly loaded on a resin to afford IIIa (Path A) or transformed to intermediate IIIb (Path B) which is subsequently (with or without modification) loaded on a resin to afford once again IIIa. Deprotection and/or oxidation of IIIa, if needed, afford target solid-supported oxidants I The polymer-supported benzoquinones I are used for the oxidation of hydroquinones to quinones, for the oxidation of benzylic alcohols the aldehydes, for the removal of p-methoxybenzyl and related protective groups, for the dehydrogenation of tetrahydronaphthalene derivatives and for the dehydrogenation of steroid 4-en-3-ones. The polymer-supported reagent after its use is regenerated upon treatment with an oxidative agent.
    这项发明提供了一种合成聚合物支持苯醌的通用方法,其结构如下所示:其中:•,X,R1,R2和R3在正文中描述。该方法的一般概念包括使用一种卤代起始物质II的通用结构(图1),通过亲核取代反应(NSR)或钯介导的偶联反应(PMC),直接加载到树脂上以得到IIIa(路径A),或转化为中间体IIIb(路径B),随后(带或不带修饰)加载到树脂上再次得到IIIa。如果需要,对IIIa进行去保护和/或氧化,得到目标固体支持氧化剂I。聚合物支持的苯醌I用于将对氢醌氧化为醌,将苄基醇氧化为醛,去除对甲氧基苄和相关保护基,脱氢四氢萘衍生物以及类固醇4-烯-3-酮的脱氢。使用后,聚合物支持试剂经过氧化剂处理后可以再生。
  • Facile Self-Assembly of Metallo-Supramolecular Ring-in-Ring and Spiderweb Structures Using Multivalent Terpyridine Ligands

    A series of metallo‐supramolecular ring‐in‐ring structures was generated by assembling CdII ions and the multivalent terpyridine ligands (L1‐3) composed of one 60°‐bent and two 120°‐bent bis(terpyridine)s with varying alkyl linker lengths. The mechanistic study for the self‐assembly process excluded an entropically templated pathway and showed that the intramolecularly complexed species is the key
    通过组装Cd II离子和由一个60°弯曲的和两个120°弯曲的双(叔吡啶)组成的多价叔吡啶配体(L 1-3)生成一系列金属超分子环内结构烷基接头长度。自组装过程的机理研究排除了熵模板化途径,并表明分子内复杂的物种是导致环环形成的关键中间产物。下一代上层结构蜘蛛网是使用细长的十(叔吡啶)配体(L 5)定量生产的。

    Three heterobimetallic metallomacrocycles were readily assembled through either a stepwise or a one-pot protocol by selective complexation of ZnII ions and PdII or PtII acceptors with the predesigned ligands possessing one 60°-bent bisterpyridine and two mono- or bis-pyridines. In the multicomponent self-assembly, the preorganized ZnII-terpyridine metallo-triangle led to the formation of the exterior
    通过将Zn II离子和Pd II或Pt II受体与预先设计的具有一个60°弯曲的二吡啶和两个吡啶的配体进行选择性络合,可以通过逐步或一锅操作方案轻松组装三个异双金属金属大环化合物。在多组分自组装中,预组织的Zn II-吡啶金属三角形导致了外部大环的形成。
