ABSTRACT One-pot multi-component synthesis of N,N′-alkylidene bisamides, 2,4,5-trisubstituted imidazoles and 1,2,4,5-tetrasubstituted imidazoles in the presence of catalytic material heteropoly-11-tungsto-1-vanadophosphoric acid (HPV) supported on activated natural clay for about 20% (HPVAC-20) under solvent-free reaction condition have been achieved. Green heterogeneous reaction condition, simple
摘要 在催化材料杂多-11-钨-1-存在下,一锅多组分合成N,N'-亚烷基双酰胺、2,4,5-三取代咪唑和1,2,4,5-四取代咪唑已经在无溶剂反应条件下实现了约 20% (HPVAC-20) 负载在活性天然粘土上的钒磷酸 (HPV)。绿色非均相反应条件、后处理程序简单、反应时间短、产物收率高、催化剂可重复使用是该方案的优点。图形概要
