Abstract Silica‐supported sodium hydrogen sulfate (NaHSO4 · SiO2) efficiently catalyzes the four‐component reaction of aryl aldehydes, enolisable ketones, acetyl chloride, and acetonitrile to form the corresponding β‐acetylamino ketones at room temperature. The catalyst is inexpensive and ecofriendly and works under heterogeneous conditions.The present methodology offers several advantages such as
摘要 二氧化硅负载的硫酸氢钠 (NaHSO4·SiO2) 在室温下可有效催化芳醛、可烯化酮、乙酰氯和乙腈的四组分反应生成相应的 β-乙酰氨基酮。该催化剂价格低廉且环保,可在非均相条件下工作。本方法提供了几个优点,如产率高、程序简单、反应时间短(1-3 小时)和条件温和。
