  Nano-SiO2@nPr@DPyE-Ni：一种用于快速生产对称二芳基硫醚和吡唑啉酮的新型纳米催化剂

  摘要：

  最初，制备了一种以纳米硅胶为基质、Ni活性中心的新型有机金属催化剂，即纳米SiO 2 @nPr@DPyE-Ni，并对其性能进行了深入的争论。然后以优异的性能应用于生产对称二芳基硫醚（14 个条目，78–98%，20–150 分钟，EtOH，70 °C）和 2-芳基-5-甲基-2,3-二氢-1 H -3-吡唑啉酮（12 个条目，91–98%，2–4 分钟，无溶剂，室温）。在两条生产路线中，纳米催化剂均可回收和重复使用七次以上，并通过回收结果、热过滤测试和ICP-OES（耦合等离子体发射光谱）方法检查和确认其异质性。 图形概要

  A simple and green process to prepare copper iodide in nano scale via sonication was carried out. Subsequently, this nanoparticles was used as an efficient catalyst for the synthesis of 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones via four-component reaction of hydrazine, ethyl acetoacetate, aldehyde and beta-naphthol in water under ultrasound irradiation. The combinatorial synthesis was attained for this procedure with applying ultrasound irradiation while making use of water as green ambient. Simple work-up, excellent yield of products and short reaction times are some of the important features of this protocol. Notably, this catalyst could be recycled and reused for five times without noticeably decreasing the catalytic activity. (C) 2013 Elsevier B.V. All rights reserved.

  A series of 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones has been synthesized by one-pot, four-component sequential reactions of phenylhydrazine, methyl acetoacetate, aromatic aldehydes and beta-naphthol in the presence of p-toluenesulphonic acid in water in good yields. These 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones were screened for in-vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (MTB) using agar dilution method. Among the 15 compounds screened, 4-[(2,4-dichlorophenyl)(2-hydroxy-1-naphthyl)methyl]-2-(4-fluorophenyl)-5-methyl-2,3-dihydro-1H-3-pyrazolone displays the maximum potency with a minimum inhibitory concentration (MIC) of 1.6 mu M against MTB, being 2.94 and 4.75 times more active than ciprofloxacin and ethambutol respectively.
