Chemical Synthesis and Reactions

A new use of ionic liquid [bdmim][PF6] as solvent for the Baylis–Hillman reaction is presented. Unlike the commonly used [bmim][PF6] that evidently reacts with electrophilic aldehydes under basic conditions, ionic liquid [bdmim][PF6] is inert and the Baylis–Hillman reaction in [bdmim][PF6] proceeds smoothly with better yield.
