The catalytic performance of the [Fe3O4@SiO2@(CH2)3-Py]HSO4was evaluated towards the regioselective thiocyanation of aromatic and heteroaromatic compounds with KSCN as a thiocyanate source afforded the corresponding aryl and heteroaryl thiocyanates derivatives 2a-n at room temperature in H2O2 as a clean oxidant and ethanol as a green solvent. A broad range of products 2a-n was synthesized high yields (up to yield 97%) under the mild reaction conditions. %U https://www.chemmethod.com/article_108149_e3eb2f7e073bef8a0c57739aa77a3a18.pdf
