Abstract

N-sulfonated cyclohexylhydantoin (NSCH), a new N-sulfonic acid compound, was prepared and characterized using FT-IR, H NMR, C NMR, UV-Vis and TGA analysis. The potential catalyst efficiency was examined, using synthesis of chromene, xanthene and hydroquinoline derivatives under solvent-free conditions. All of the examined model reactions gave excellent yields, and required short reaction times. Simple catalyst preparation and work-up under mild reaction condition, with low cost and the ability to recover the catalyst for reuse without significant loss of activity are some of the notable advantages of the introduced catalyst.
2,4-二氧基-1,3-重氮斯皮罗[4,5]癸烷-3-磺酸作为新型固相无卤酸催化剂的制备、表征及评价
制备了一种新型n -磺酸类化合物n -磺化环己基海因(NSCH),并用FT-IR、H - NMR、C - NMR、UV-Vis和TGA对其进行了表征。考察了在无溶剂条件下合成铬、杂蒽和对苯二酚衍生物的潜在催化剂效率。所有测试的模型反应都有很好的产率,反应时间短。催化剂制备简单、反应条件温和、成本低、催化剂可回收再利用而不显著损失活性是本发明催化剂的显著优点。
