摘要
在无溶剂条件下利用氢氧化钠和碳酸钾混合碱作为催化剂,使用研磨技术促进2-硝基苯甲醛和苯乙酮衍生物的固相羟醛缩合,得到了14种2-硝基查尔酮类衍生物。该法反应时间短,操作简便,收率好。
Using the grinding method fourteen derivatives of 2-nitrechalcone were obtained with the aldol condensation of benzaldehyde and acetophenone in the presence of NaOH and K2CO3 mixed catalyst under solvent-free condition. These reactions were completed in 10～30min with ease and good yields.
