Preparation of pyridinium-based ionic liquid and application as a green catalyst for the synthetic route of 4<i>H</i>-1-benzopyran-5(6<i>H</i>)-ones

1-(4-sulfobutyl)pyridinium chlorozincate ionic liquid was synthesised in high yield (89%) through a simple route and characterised using FT-IR, NMR, and HRMS spectroscopy. The one-pot reaction was employed for the condensation reaction of benzaldehydes, 5,5-dimethyl-1,3-cyclohexanedione, and dicyan...
