Yarmohammadi, Nasrin published the artcileCopper based on diaminonaphthalene-coated magnetic nanoparticles as robust catalysts for catalytic oxidation reactions and C-S cross-coupling reactions, Name: 2,2′-Dithiodibenzoic acid, the publication is RSC Advances (2021), 11(16), 9366-9380, database is CAplus and MEDLINE.
In this work, the immobilization of copper(II) on the surface of 1,8-diaminonaphthalene (DAN)-coated magnetic nanoparticles provided a highly active catalyst for the oxidation reaction of sulfides to sulfoxides and the oxidative coupling of thiols to disulfides using hydrogen peroxide (H2O2). This catalyst was also applied for the one-pot synthesis of sym. sulfides via the reaction of aryl halides with thiourea as the sulfur source in the presence of NaOH instead of former strongly basic and harsh reaction conditions. Under optimum conditions, the synthesis yields of sulfoxides, sym. sulfides, and disulfides were about 99%, 95%, and 96% resp. with highest selectivity. The heterogeneous copper-based catalyst has advantages such as the easy recyclability of the catalyst, the easy separation of the product and the less wastage of products during the separation of the catalyst. This heterogeneous nanocatalyst was characterized by FESEM, FT-IR, VSM, XRD, EDX, ICP and TGA. Furthermore, the recycled catalyst can be reused for several runs and was economically effective.
