Abstract :
Reusable silica supported HClO4 and KHSO4 materials have been explored as green catalysts for thiocyanation of aromatic compounds under conventional and solvent free microwave assisted conditions. The microwave assisted protocol exhibited remarkable rate accelerations and offered selective thiocyanation of aromatic and heteroaromatic compounds with good yields. The developed protocols are also promising and comparable with the existing procedures.
