A Practical Synthesis of Arylthiocyanates from Arenesulfinates or Arenesulfonyl Chlorides with Cyanotrimethylsilane

Abstract

Preparation of arylthiocyanates by simply mixing aromatic sulfinates with cyanotrimethylsilane (TMSCN) was achieved in good to moderate yields. The thiocyanates were also obtained directly from sulfonyl chloride using TMSCN, sodium sulfite, and potassium carbonate.
