The versatility of trimethylsilyl isothiocyanate (TMSNCS) as a reagent is impressive, especially in heterocycle synthesis. TMSNCS is also commonly used in reactions of thiocyanation and isothiocyanation. The advantages of TMSNCS are moderated toxicity, chemical stability, high tolerance with other functional groups, and ease of handling. This paper highlights a selection of many different and recently reported types of reactions that this reagent is able to promote.
