Nano titania-supported sulfonic acid (n-TSA) has found to be a highly efficient, eco-friendly and recyclable heterogeneous nanocatalyst for the solvent-free synthesis of 2,4,6-triarylpyridines through one-pot three-component reaction of acetophenones, aryl aldehydes and ammonium acetate. This reported method illustrates several advantages such as environmental friendliness reaction conditions, simplicity
纳米二氧化钛负载的磺酸(n-TSA)被发现是一种高效,生态友好且可回收的多相纳米催化剂,可通过一锅三苯乙酮反应无溶剂合成2,4,6-三芳基吡啶,芳基醛和乙酸铵。该报道的方法说明了许多优点,例如环境友好的反应条件,简单,反应时间短,易于后处理,催化剂的可重复使用性和产物的高产率。也报道了一种新化合物。此外,该催化剂可以在简单的后处理之后再循环,并且在不显着降低其催化活性的情况下重复使用至少六次。
