Deshmukh Received: 13 January 2015 / Accepted: 11 March 2015 / Published online: 22 April 2015 Springer Science+Business Media Dordrecht 2015 Abstract Protic ionic liquids (PILs), which are easily produced through the combi- nation of a Brønsted acid and Brønsted base, such as [Mim]Ac and 1,4-diazabicy- clo[2.2.2]octane (DABCO):AcOH:H 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.
