中文摘要:
      在无溶剂条件下以NH4H2PO4-SiO2催化芳醛、联苯酰和乙酸铵三组分缩合,一锅法合成了2,4,5三芳基-( 1H) -咪唑. 此法操作简单,收率高,无需使用溶剂,催化剂便宜、无毒、可重复使用.
英文摘要:
      NH4H2PO4-SiO2 was used as an efficient and recyclable catalyst for one-pot synthesis of 2,4,5-triaryl-1Himidazoles by three-component condensation of benzil,aldehydes and ammonium acetate under solvent-free conditions. Thismethod has a simple operation and high yields,without use of solvents. And the catalysts is cheap,non-toxic and reusable.
