Abstract
A simple microwave-accelerated condensation of 2-aminothiophenol and aromatic aldehydes in an inexpensive ionic liquid, 1-pentyl-3-methylimidazolium bromide ([pmIm]Br) provides 2-arylbenzothiazoles under solvent and catalyst-free condition. The ionic liquid can be recycled for subsequent reactions.
