Abstract
FeCl3 catalyzes a solvent-free sulfonylation of arenes under microwave irradiation. With more reactive and/or nonvolatile substrates (anisole, xylenes, mesitylene) a short reaction time at constant MW power without control of the temperature was used. With less reactive and/or low-boiling reagents (benzene, toluene, halobenzenes), the MW power was controlled. A nonthermal effect was not observed.
