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.
Arenethiocyanate can be prepared by reaction of trimethylsilylcyanide with sodium arenesulphinate or arenesulphonyl chloride.

A novel electrophilic thiocyanating reagent, N-thiocyanato-dibenzenesulfonimide, was prepared and exhibited enhanced electrophilicity with a wide scope of substrates. Thus, it reacted with activated aromatics such as phenols, indoles, anilines and anisoles without a catalyst giving the corresponding thicyanate derivatives in high yields, while TfOH for unactivated arenes and hetero aromatics and Zn(OTf)2
