## Abstract magnified image The oneโpot direct synthesis of 2โaminobenzothiazoles from phenyl isothiocyanate and amines using a new reagent of 1โbutylโ3โmethylimidazolium tribromide ([Bmim]Br~3~) in ionic liquid 1โbutylโ3โmethylimidazolium tetraflouoroborate ([Bmim]BF~4~) is described.
Aldehydes and mercaptoacetic acid are coupled in the presence of a catalytic amount of economical and non-toxic molecular iodine in [bmim][BF 4 ] ionic liquid under mild conditions to afford the corresponding 1,3-oxathiolan-5-one in excellent yields. Molecular iodine acts faster in ionic liquids whe
