Heterogeneous and Catalytic Thiocyanation of Aromatic Compounds in Aqueous Media
Phosphorus, sulfur, and silicon and the related elements Vol. 187, No. 3, 295–304
چکیده
This article describes a highly efficient heterogeneous catalytic thiocyanation of indoles, substituted anilines (electron rich and electron deficient) and N-substituted aromatic amines in water under mild and green conditions. The reaction of substrates with KSCN in the presence of silica sulfuric acid (SSA) and silica boron sulfonic acid (SBSA) as heterogeneous catalysts and H2O2 or UHP (urea hydrogen peroxide) as green oxidants produces aryl thiocyanates in short reaction times and high yields. Moreover, in this article, some novel aryl thiocyanates were synthesized.
