A microwave-assisted direct coupling between aryl halides and carbondisulfide in ionic liquid [DBUH]+[OAc]− (DBU = 1,8-diazabicyclo-[5.4.0] undec-7-ene) has been developed. The reactions are very efficient, affording the corresponding diaryl thioethers in moderate to high yields. Aryl chlorides could also be reacted with carbondisulfide using this protocol. Moreover, [DBUH]+[OAc]− could be easily
