Reusable Silica supported Perchloric acid and potassium bisulphate as green catalysts for thiocyanation of aromatic compounds under solvent free conditions

Journal Title: Iranian Chemical Communication - Year 2017, Vol 5, Issue 3

Abstract

Reusable silica supported perchloric acid and potassium bisulphate have been prepared and 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 hetero aromatic compounds in good yields. Reaction times observed in conventional methods range of 2.0 to 6.0 hours, which reduced to only few minutes (1 to 3 min) in microwave assisted reactions. The developed protocols are also promising and comparable with the existing procedures. Prepared catalysts could be easily recycled for five time with a reproducible efficiency.
