A green synthesis of nitrones in glycerol
MONIRE SHARIATIPOUR MASOUMEH JADIDINEJAD AKBAR HEYDARI
An eco-friendly and efficient synthesis of nitrones is presented by condensation of an equimolar amount of aldehydes and N-substituted hydroxylamine hydrochlorides in glycerol as a recyclable solventcatalyst. This novel protocol provides rapid and mild access to a series of nitrone derivatives in good to excellent yields in the absence of catalyst and base.

Diphenyl phosphate creatine immobilized on magnetite nanoparticles: an efficient and recyclable catalyst for Aza-Michael reaction
FARZANE PAZOKI FAHIMEH MOHAMMADPANAH AREFE SALAMAT MANESH JAMSHID AZARNIA MEHRABAN AKBAR HEYDARI
In this paper, diphenyl phosphate creatine was successfully immobilized on Fe3O4 nanoparticles and used as the highly efficient catalyst for the aza-Michael reaction of 5-substituted tetrazole and a,bunsaturated carbonyl. The prepared nanocatalyst was fully analyzed by various techniques such as FouriertransformInfrared Spectroscopy (FT-IR), Field Emission Scanning electron microscope (FE-SEM), Vibrating Sample Magnetometer (VSM), Thermal Gravimetric Analysis (TGA) and X-ray Diffraction (XRD). This procedure possesses numerous advantages such as simple work-up, high yield and short reaction times.

1, 4-Diazabicyclo[2.2.2]octane-sulfonic acid immobilized on magnetic Fe3O4@SiO2 nanoparticles: a novel and recyclable catalyst for the one-pot synthesis of 4-aryl-NH-1, 2, 3-triazoles
MASOUMEH JADIDI NEJAD FARZANE PAZOKI SEPIDEH BAGHERI ELAHE YAZDANI AKBAR HEYDARI
In this study, the surface of silica-coated magnetic nanoparticles (Fe3O4@SiO2) were successfully functionalized by an organic ligand of 1, 4-Diazabicyclo[2.2.2]octane (DABCO)-sulfonic acid and used as ahighly efficient catalyst for the synthesis of 4-aryl-NH-1, 2, 3-triazoles from the benzyl alcohol derivatives,nitromethane and sodium azide in ethanol. Furthermore, this catalyst could be recovered and reused five times without noticeable loss of activity
