  • Ultrasound-Assisted Preparation of Copper(I) Oxide Nanocubes: High Catalytic Activity in the Synthesis of Quinazolines
    作者:Amol B. Raut、Abhishek R. Tiwari、Bhalchandra M. Bhanage
    DOI:10.1002/cctc.201601330
    日期:2017.4.7
    energy‐dispersive X‐ray spectroscopy, UV/Vis spectroscopy, differential scanning calorimetry with thermogravimetric analysis, and FTIR spectroscopy. The Cu2O nanocubes were employed as a heterogeneous nanocatalyst and were found to be highly active in the preparation of quinazolines by the tandem cyclization of 2‐bromobenzaldehydes with amidines under ligand‐free conditions. Various quinazolines could be prepared
    提出了一种在室温下简便,绿色的超声辅助合成Cu 2 O纳米立方体的方法。使用XRD,SEM,TEM,能量色散X射线光谱,UV / Vis光谱,带热重分析的差示扫描量热法和FTIR光谱对Cu 2 O纳米立方体进行了表征。Cu 2 O纳米立方体被用作非均相纳米催化剂,并且在无配体的条件下,通过将2-溴苯甲醛与am串联环化,发现在制备喹唑啉中具有很高的活性。可以在非常短的时间内以优异的收率制备各种喹唑啉。此外,Cu 2纳米催化剂可以循环使用多达四次,而不会显着降低催化活性。

    日期:2014.5
    between 1-(2-bromophenyl)methanamines and amidines using K3PO4 as the base, pivalic acid as the additive, and aerial oxygen as the oxidant gives access to substituted quinazolines in a single step with yields in the range between 43 and 90%. It is assumed that the reaction proceeds as a Cu(I)-catalyzed intermolecular N-arylation followed by an intramolecular nucleophilic substitution and a Cu(II)-catalyzed
    以K 3 PO 4为碱,新戊酸为添加剂,空气中的氧气为氧化剂的1-(2-溴苯基)甲胺和am之间的CuI催化的多米诺反应使一步反应可得到取代的喹唑啉范围介于43%和90%之间。假定该反应以Cu(I)催化的分子间N-芳基化进行,然后进行分子内亲核取代和Cu(II)催化的氧化。am可以被酰亚胺取代,反应也可以与1-(2-碘苯基)甲胺一起进行。
