Protic ionic liquids: a lucid, rational tool for synthesis of phthalazinediones, quinoxalines and benzopyrans

Protic ionic liquids (PILs), which are easily produced through the combination of a Brønsted acid and Brønsted base, such as [Mim]Ac and 1,4-diazabicyclo[2.2.2]octane (DABCO):AcOH:H 2 O (1:1:3), were found to be lucid, tunable tool for synthesis of various heterocyclic motifs such as phthalazinedion...

Zusammenfassung:Protic ionic liquids (PILs), which are easily produced through the combination of a Brønsted acid and Brønsted base, such as [Mim]Ac and 1,4-diazabicyclo[2.2.2]octane (DABCO):AcOH:H 2 O (1:1:3), were found to be lucid, tunable tool for synthesis of various heterocyclic motifs such as phthalazinediones, quinoxalines and benzopyrans. These PILs were found to be efficient for synthesis of diverse heterocyclic derivatives, along with demonstrating noteworthy aspects such as high yields, isolation of pure products without column chromatography and recyclable reaction media.
