Application

1-Methylimidazolium hydrogen sulfate serves as a versatile Brønsted acidic ionic liquid with multiple applications. It acts as a crucial component in catalytic systems alongside chlorotrimethylsilane, facilitating the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and hydroquinazoline-2,5-diones. Additionally, this ionic liquid functions as a catalyst in producing biologically significant 2,5-dimethyl-N-substituted pyrroles and is valued for its reusability in synthesizing spiro[indoline-3',2-quinazoline]2',4(3H)-dione. Furthermore, it is employed in the metal recovery process, specifically the leaching of copper and zinc from brass dross, using hydrogen peroxide as an oxidizing agent.
