Nanomagnetic reusable catalysts in organic synthesis

Research on the catalytic activity of MNP-[Dop-OH]-CuBr2 nanocomposites: novel and stable reusable nanocatalysts for the synthesis of 1,3,5-triazine derivatives

“…12 During the last decade, the immobilization of metallic catalysts such as copper, palladium, nickel and zinc on the surface of Fe 3 O 4 nanoparticles modied with ligands has been widely utilized as an efficient and attractive catalytic strategy for the performance of chemical reactions. [13][14][15] Owing to the importance of heterocyclic compounds in medicinal chemistry and the synthesis of pharmaceutical and chemical compounds, the synthesis of these compounds is always one of the important goals of organic chemists. [16][17][18] Triazine cores are a very important part of antimicrobial, analgesic and anti-inammatory drugs.…”

Investigation of Fe3O4@boehmite NPs as efficient and magnetically recoverable nanocatalyst in the homoselective synthesis of tetrazoles

“…More important, at the end of the reaction, they are quickly, easily and completely recovered from the reaction mixture using an external magnet. [11][12][13][14][15][16] But these MNPs are not very stable for long times. 17 Therefore, many organic or inorganic covers have been used to increase the MNPs stability.…”

Magnetic Nanoparticles Linked to Pyridinium Hydrotribromide Groups as Catalysts for Selective Oxidation of Alcohols and Protection of Alcohols

“…This can solve the problems associated with nanoparticle separation. 25,26 Although several immobilized tribromides have been synthesized, in most cases their preparation involves the use of liquid Br 2 and/or HBr, 16,[21][22][23][24] which leads to an environmental problem. Numerous improved methods for the synthesis of organic tribromides have been described in the literature and are considered to be environmentally friendly.…”
