摘要

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.
