In this work, succinimidinium hydrogensulfate ([H-Suc]HSO4), a newly reported Brönsted acidic ionic liquid, is used as an efficient and reusable catalyst in the synthesis of tetrahydrobenzimidazo[2,1-b]quinazolin-1(2H)-ones, 1-(benzothiazolylamino)phenylmethyl-2-naphthols, 1,8-dioxo-octahydroxanthenes and bis(indolyl)methanes. All reactions were performed during relatively short reaction times with
在这项工作中,新报道的布朗斯台德酸性离子液体硫酸氢琥珀酰亚胺([H-Suc] HSO 4)在合成四氢苯并咪唑并[ 2,1- b ]喹唑啉-1(2 H)中用作有效且可重复使用的催化剂。)-,1-(苯并噻唑基氨基)苯基甲基-2-萘酚,1,8-二氧-八氢氧杂蒽和双(吲哚基)甲烷。所有反应均在相对短的反应时间内进行,并具有优异的收率。通过IR,1 H NMR和13 C NMR光谱对产物的结构进行表征,并通过比较真实样品进行确认。
