Abstract
Palladium-catalysed carbonylation of aryl halides with alcohols or NEt2H pr oceeds in ionic liquid media (1-butyl-3-methylimidazolium tetrafluoroborate or hexafluorophosphate). The catalyst/ionic liquid mixture could be recycl ed, after separation of the product by either distillation or extraction wi th ether. Carbonylation with alcohols forming benzoates was greatly acceler ated by the use of ionic liquid.
