ABSTRACT The sulfonylation reaction of various aliphatic, alicyclic, aromatic, and hetero-aromatic amines with p-acetamidobenzenesulfonyl chloride has been investigated using different types of base catalysis under varied reaction conditions. Mg–Al hydrotalcite, characterizable as an inexpensive, reusable, and green solid catalyst, was found to be the most efficient catalyst, when the reaction is carried
摘要 使用不同类型的碱催化在不同反应条件下研究了各种脂肪族、脂环族、芳香族和杂芳香族胺与对乙酰氨基苯磺酰氯的磺酰化反应。当反应在最小体积的溶剂(丙酮)中进行时,Mg-Al 水滑石是一种廉价、可重复使用的绿色固体催化剂,被发现是最有效的催化剂。发现在超声辐射的支持下反应显着加速,以比在更持久的常规搅拌条件下获得的产率更好或相等的产率提供磺酰胺。图形概要
