    Reactions of 3-diazo-1,3-dihydro-2H-indol-2-one derivatives with enaminones. A novel synthesis of 1,2,3-triazoles
    摘要:
    A new and efficient method of 1,2,3-triazole synthesis is described in which these heterocyclics are formed through a novel nitrogen transfer from diazocarbonyl compounds to enaminones. Thus, the reaction of 3-diazo-1,3-dihydro-2H-indol-2-one derivatives 1 (X = NR3) and 3-diazobenzo[b]-thiophen-2(3H)-one 5 (X = S) with enaminones 2 and 7 leads to the formation of mainly 1,2,3-triazoles 4 and pyrazoloquinazolinones 3. Both the phenyl substituents (Y and Z in 1) and the nature of the X group affects the reaction rate and product distribution. Rate increases with an increase in the electron-withdrawing ability of the substituents Y and Z. The dinitro derivative 1g is shown to be the most efficient in promoting 1,2,3-triazole 4 formation while pyrazoloquinazolinones 3 are often competitively formed when other derivatives of 1 are employed.

    Bimetallic nanoparticles, particularly those based on copper, have recently attracted a great deal of attention for the development of low cost and highly active catalysts due to the synergistic interaction between individual metal components. In this work, bimetallic Ag–Cu alloy nanoparticles were explored as a highly active and reusable catalyst for the enamination of 1,3-dicarbonyls using diverse
    双金属纳米颗粒,特别是基于铜的双金属纳米颗粒,由于各个金属组分之间的协同相互作用,最近引起了人们的广泛关注,以开发低成本和高活性的催化剂。在这项工作中,双金属Ag-Cu合金纳米颗粒被研究为一种高活性和可重复使用的催化剂,用于使用多种胺来引发1,3-二羰基。通过紫外可见光谱,X射线衍射(XRD),高分辨率透射电子显微镜能量分散光谱(HRTEM-EDS)以及价带和核能级X射线光电子对纳米催化剂进行了深入的表征。光谱仪(XPS)来研究双金属结构和成分的影响。与单金属Ag和Cu纳米粒子相比,合金化的Ag-Cu纳米颗粒显示出高催化性能,并且所产生的催化活性取决于Ag与Cu的比例。这种增强的催化活性应该与由于银和铜纳米颗粒之间的紧密接触而形成的银和铜纳米颗粒之间的电子相互作用有关。我们的研究可为设计用于精细化学合成的高效合金纳米催化剂奠定基础通过引诱反应。
  • Studies on Enaminoketones
    作者:Ivo Jirkovsky
    DOI:10.1139/v74-009
    日期:1974.1.1

    A series of N-substituted 3-amino-2-cyclohexen-1-ones and 3-amino-5,5-dimethyl-2-cyclohexen-1-ones (1–9) has been prepared. Halogenation of these compounds with bromine, NBS, cyanogen bromide, and iodine is described. The tendency of enaminoketones to form salts of the corresponding enol-ketimine form was observed and structures of the salts are supported by their p.m.r. and i.r. properties. The reaction of 3-benzylamino-2-bromo-5,5-dimethyl-2-cyclohexen-1-one with concentrated sulfuric acid effected debenzylation. Treatment of 3-benzylamino-2-iodo-5,5-dimethyl-2-cyclohexen-1-one with dibenzoyl peroxide gave 8,8a-dihydro-5-iodo-8,8-dimethyl-2,3-diphenyl-4H-1,4-benzoxazine-6,7-diol. The above secondary enaminoketones 1–9 were shown to react with phenyl isocyanates, phenyl isothiocyanate. and methyl isothiocyanate under fusion conditions to yield substituted 2-amino-6-oxo-1-cyclo-hexene-1-carboxamides and corresponding thiocarboxamides. 2-Benzylamino-6-oxo-N-phenyl-1-cyclohexene-1-carboxamide and its 5,5-dimethyl analog were found to undergo facile transamination in position 2, when heated with a primary amine. This reaction is of synthetic utility for the preparation of biologically active derivatives with a basically substituted side chain. Addition of 4-methylamino-3-pentene-2-one to phenyl isocyanate afforded 2-acetyl-3-methylaminoisocrotonanilide; the spectroscopic properties of this product are discussed.
