Abstract

Six different room temperature ionic liquids (RTILs) based on N-methyl or N-isopropyl imidazolium cations with counteranions, such as BF4-, PF6-, and OTf−, have been synthesized by exchanging the counteranions of the corresponding N-methyl or N- isopropylimidazolium bromides using appropriate salts such as NH4BF4, KPF6, and AgOTf. Catalytic amounts of these ionic liquids (ILs) have been used as the reaction medium for ...
