Abstract

Tetrabutyl phosphonium sulfate ([TBP]2SO4), as novel room-temperature ionic liquid (RTIL), was synthesized by a simple cost-effective method, characterized by 1H, 13C, 31P NMR and FT-IR spectrophotometry. The newly prepared catalyst was used as an efficient catalyst in some four multicomponent reactions (4MCRs) e. g., to synthesis pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine. This green method has several advantages such as short reaction time, using simple methods to prepare catalysts and products, easy operation and high efficiency of products. In addition, the catalyst can be easily recovered and reused several times with reduced average activity.

[TBP] 2 SO 4 离子液体催化剂用于哒嗪并吲唑、吲唑并酞嗪和吡唑并酞嗪衍生物的4MCR

摘要

硫酸四丁基鏻 ([TBP] 2 SO 4 ) 作为一种新型室温离子液体 (RTIL),通过1 H、13 C、31 P NMR 和 FT-IR 分光光度法表征,采用简单经济的方法合成。新制备的催化剂在某些四种多组分反应 (4MCR) 中用作高效催化剂,例如合成哒嗪并[1,2- a ]吲唑、吲唑并[2,1- b ]酞嗪和吡唑并[1,2 - b ]]酞嗪。这种绿色方法具有反应时间短、催化剂和产品制备方法简单、操作简便、产品效率高等优点。此外,催化剂可以很容易地回收和多次重复使用,平均活性降低。
