Abstract

Silica vanadic acid (in which vanadium oxytrichloride has been supported on silica) is applied as an efficient, reusable and heterogeneous catalyst for the thiocyanation of heterocycles, substituted anilines (electron-rich and electron-deficient) and N-substituted aromatic amines using hydrogen peroxide in the water as a solvent at room temperature. The catalyst can be easily recovered and reused for ten reaction cycles without ...
