    摘要 通过主客体相互作用,首次实现了对酸性荧光受体咖啡因、可可碱和茶碱三种黄嘌呤生物碱的识别。设计的受体基于选择不同的荧光团作为间隔基,这些荧光基团可以在结合的酚羟基或羧基之间容纳双环黄嘌呤客体。在所有黄嘌呤生物碱中,咖啡因是最强的碱,尽管咖啡因的所有氮都被甲基化,但其结合常数最大。通过光化学将反式异构体转化为顺式异构体,从而产生空腔以更好地结合黄嘌呤生物碱。受体 4-4-[4'-(3-Carboxypropoxy)phynylazo]phenoxy}butyric acid (5) 已被证明在增强与咖啡因络合的荧光强度方面最有效。结合实验技术如紫外-可见光谱和荧光光谱已经研究了结合特性。还描述了受体 4,4'-二氮烯基二酚 (4) 和咖啡因之间的固态结合性能。图形概要

  • Ruthenium complexes with naphthyridine ligands. Synthesis, characterization and catalytic activity in oxidation reactions †
    作者:Alexandra E. M. Boelrijk、Thomas X. Neenan、Jan Reedijk
    DOI:10.1039/a702983g
    日期:——
    New ruthenium complexes with 1,8-naphthyridine (napy) or derivatives thereof as ligands have been prepared and characterized. Three groups of complexes were obtained. The first consists of three dinuclear ruthenium complexes with two ligands (1,8-naphthyridine and pyridopyrazine) co-ordinated to two ruthenium ions in a bridging fashion. The second consists of two ruthenium dinuclear complexes having one ligand (2,7-dimethoxy- or 2,7-dichloro-1,8-naphthyridine, abbreviated to dmnapy and dcnapy respectively) co-ordinated to two ruthenium atoms. Proton NMR spectra for both complexes in aqueous solution and in acetonitrile revealed the conversion of a symmetrical form, suggesting dinucleating behaviour of the ligand, into an asymmetrical form, suggesting mononucleating behaviour of the ligand. The third group consists of a mono- and a di-nuclear complex with the ligand 2,7-di(phenylazo)-1,8-naphthyridine. The catalytic activity of the novel naphthyridine complexes in oxidation reactions has been studied. The catalytic oxidation of alcohols and the epoxidation of trans-stilbene were examined and the different reaction rates and selectivities are discussed in a comparative way. The active high-valent species resulting from the [Ru2(napy)2(H2O)4Cl(OH)]4+ complex is discussed in more detail.
    以 1,8-萘啶(napy)或其衍生物为配体的新型钌配合物已经制备完成,并对其进行了表征。共获得三组配合物。第一组由三个双核钌配合物组成,其中两个配体(1,8-萘啶和吡啶并嗪)以桥接方式与两个钌离子配位。第二种由两个钌二核配合物组成,其中一个配体(2,7-二甲氧基-或 2,7-二氯-1,8-萘啶,分别简称为 dmnapy 和 dcnapy)与两个钌原子配位。这两种配合物在水溶液和乙腈中的质子核磁共振光谱显示,配体由对称形式转化为不对称形式,表明配体具有双核作用。第三组由配体 2,7-二(苯基偶氮)-1,8-萘啶的单核和双核配合物组成。研究了新型萘啶配合物在氧化反应中的催化活性。研究考察了醇的催化氧化反应和反式二苯乙烯的环氧化反应,并对不同的反应速率和选择性进行了比较讨论。更详细地讨论了[Ru2(napy)2(H2O)4Cl(OH)]4+ 复合物产生的活性高价物种。

    We report the synthesis, characterization and coordination chemistry of a new naphthyridine-derived phosphinite PONNOP expanded pincer ligand. As envisioned, the dinucleating ligand readily binds two copper(I) centers in close proximity, but undergoes an unexpected rearrangement in the presence of nickel(II) salts to form an interesting PONNP pincer platform.
