    AbstractCyan‐acetessigsäure‐t‐butylester liefert bei Heizen rnit wenig Toluolsulfonsäure in Benzol die kristallisierte α‐Cyan‐acetessigsäure, die in unpolaren Lösungsmitteln relativ stabil ist. In Wasser erfolgt momentan Decarboxylierung zu Cyanaceton, das auf diese Weise leicht rein herzustellen ist.

  • The Formation of Pyrazolo[1,5-<i>a</i>]pyrimidine Derivatives
    作者:Isaburo Hori、Koji Saito、Hiroshi Midorikawa
    DOI:10.1246/bcsj.43.849
    日期:1970.3
    The combination reactions of 3-alkyl-2-cyano-3-methoxyacrylic esters (I) and their 3-hydrazino derivatives (II) in the presence of pyridine in alcohol at room temperature mostly gave chain intermediates, whose cyclizations led to the formation of only 2,7-dialkyl-5-hydroxypyrazolo-[1,5-a]pyrimidine derivatives. On the other hand, the reaction of Ia (3-Me) with the 5-aminopyrazole derivative (IIIa) obtained by the cyclization of IIa (3-Me) gave 7-hydroxy- and 7-aminopyrazolopyrimidine derivatives in alcohol under reflux via an intermediate. The reactions of 2-cyano-3-ethoxycrotononitrile with IIa or IIIa both afforded 7-aminopyrazolopyrimidine derivatives directly.
    在室温下,3-烷基-2-氰基-3-甲氧基丙烯酸酯(I)与它们的 3-肼基衍生物(II)在吡啶存在下在乙醇中发生的结合反应大多产生链中间体,其环化反应只导致形成 2,7-二烷基-5-羟基吡唑并-[1,5-a]嘧啶衍生物。另一方面,Ia(3-Me)与 IIa(3-Me)环化得到的 5-氨基吡唑衍生物(IIIa)反应,在醇中通过中间体回流得到 7-羟基和 7-氨基吡唑嘧啶衍生物。2-Cyano-3-ethoxycrotononitrile 与 IIa 或 IIIa 反应均可直接得到 7-氨基吡唑嘧啶衍生物。
  • Quantum Yields over 80% Achieved in Luminescent Europium Complexes by Employing Diphenylphosphoryl Tridentate Ligands

    Four tridentate europium(III) complexes containing a diphenylphosphoryl group are prepared with strong bonding between the ligands and centered ion, convinced by crystal structures. Compared to their parent bidentate complexes, the tridentate complexes display improved and exceptionally high photoluminescence quantum yields (PLQYs) in powder (all over 80%, best 91%), as well as in a CH2Cl2 solution
