Abstract

Six room temperature ionic liquids (RTILs) comprised of a tetraalkylphosphonium cation ( tridecylmethyphosphonium or trihexyltetradecylphosphonium) and a trihalide anion (Br3−, BrCl2−, or ClBr2−) have been prepared and characterized. Their ability to effect halogenation reactions with a variety of substrates has been explored. In general, halogenation reactions of alkenes proceed with high yields and stereo-and ...
