[ 1 ] - Magnetic nanoparticles containing Manganese salophen complex as an selective and recyclable catalyst for epoxidation of alkenes
A magnetically recoverable catalyst consisting of Mn (III) salophen complex was prepared. The synthesized catalyst was characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and Fourier transform infrared (FT-IR). The immobilized catalyst was shown to be an ef...

[ 3 ] - Efficient synthesis of β-hydroxy thiocyanates from epoxides and ammonium thiocyanate using 1,4-bis(triphenylphosphonium)-2-butene dichloride as a new catalyst
1,4-bis(triphenylphosphonium)-2-butene dichloride was developed as a new phase transfer catalyst. This quaternized phosphonium salt catalyzed the regioselective ring opening of epoxides by thiocyanate ion to give β-hydroxy thiocyanates in high yields under mild conditions.
[ 4 ] - Preparation and application of HMCM-22 zeolite as an efficient solid acid catalyst for the synthesis of acetals
HMCM-22 with a Si:Al molar ratio of 15:1 has been shown to effectively catalyze the synthesis of acetals with 100% selectivity by the reaction of aldehydes with methanol under reflux conditions. Platelet HMCM-22 particles were prepared by the static strategy and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), BET tech...
[ 5 ] - Fe3O4@SiO2@Am-PPC-SO3H] [HSO4]: A new magnetic solid acid nanocatalyst for the synthesis of benzoxazole derivatives
A novel magnetite nanoparticle-based heterogeneous acidic catalyst [Fe3O4@SiO2@Am-PPC-SO3H] [HSO4] was successfully prepared and characterized by SEM, EDX, TGA, VSM and FT-IR techniques. The magnetically retrievable and sustainable catalyst was investigated in the reaction of aldehyde and o-aminophenol for the synthesis of benzoxazoles. The...
