Sulfonic acid functionalized over biguanidine fabricated silica-coated heterogeneous magnetic nanoparticles (NP@SO3H) have been synthesized, well characterized and explored for the first time, as an efficient and recyclable catalyst for N-formylation of primary amines under mild reaction conditions.
The highly efficient transamidation of primary amides, phthalimide, urea and thiourea with amines catalyzed by magnetic Fe3O4@Fe(OH)3 nanoparticles is described.
Herein, we present the synthesis of Pd–CuFe2O4 magnetic nanoparticles as an efficient and recyclable catalyst for the oxidative homocoupling of various terminal alkynes to form symmetric 1,3-diynes.
Pd-BIP-γ-Fe2O3@SiO2 was used successfully as an air- and moisture-stable magnetically recyclable catalyst for Heck, Suzuki and Sonogashira coupling reactions.
