Abstract

A simple and highly efficient method for the Friedel-Crafts alkenylation of aromatic compounds has been developed by using a metal triflate (OTf) catalyst in an ionic liquid (see scheme, bmim = 1-butyl-3-methylimidazolium). Not only is the catalytic activity significantly enhanced in the ionic liquid and by-product formation decreased, but some reactions that were not possible in conventional organic solvents were shown to proceed smoothly.
