The present invention relates to chemical compounds comprising a [Y(CHRa)n—CH(Ra)SO3]− anion, their preparation and application. The chemical compounds are preferably ionic liquids.
An efficient route to prepare ionic liquids with chloroalkylsulfonate anions is presented; the synthesis proceeds in a one-step ring-opening reaction of sultones with an organic chloride salt and provides a very attractive access to new anion functionalised ionic liquids.
