We introduce a simple and efficient procedure for preparation of (1-H-3-methyl-imidazolium hydrogen sulfate) as a Bronsted acidic ionic liquid using 1-methylimidazole in the presence of concentrated sulfuric acid. Further, this Bronsted acidic room temperature ionic liquid has been employed as a catalyst for the synthesis of 1,1-diacetates from aldehydes under mild and solvent-free conditions at room temperature.
