Ionic liquids have been used as catalysts for Blanc reaction of toluene. The effects of reaction temperature, reaction time and dosage of the ionic liquid catalyst have been investigated, and the catalytic performance of different ionic liquid catalysts for toluene chloromethylation was also studied. The reaction was found to proceed under mild conditions with excellent conversion (up to 90%) in the absence of Lewis acids. The ionic liquids could be recycled and reused without loss of their catalytic activities.

5-Hydr­oxy-1-methyl-3,4-dihydro-2H-pyrrolium hydrogensulfate

Yanxiong Fang; Huarong Huang; Zhi-Yun Du; Baohua Huang; Kun Zhang

The title compound, C5H10NO+·HSO4 −, has been synthesized by reaction of 1-methylpyrrolidin-2-one with H2SO4 in a 1:1 molar ratio. The substituted pyrrolium ring adopts an envelope conformation. The hydrogensulfate anions form infinite helical chains parallel to the a axis via strong O—H⋯O hydrogen bonds. The pyrrolium cations are pendant from the chains. These cations are the hydrogen donors in the strong O—H⋯O hydrogen bonds to the hydrogensulfates. In addition, there are weak C—H⋯O hydrogen bonds in the structure.
