Abstract :
A Brønsted acidic ionic liquid-[Hmim]HSO4 promoted unexpected reaction of Baylis–Hillman alcohols and diarylmethanols with p-toluenesulfonylmethyl isocyanide (TosMIC) affording the corresponding sulfone derivatives instead of N-tosylmethyl amides is reported. After isolation of the product, the ionic liquid [Hmim]HSO4 was easily recycled for further use.
