Diphenyl phosphate creatine immobilized on magnetite nanoparticles: an efficient and recyclable catalyst for Aza-Michael reaction

In this paper, diphenyl phosphate creatine was successfully immobilized on Fe 3 O 4 nanoparticles and used as the highly efficient catalyst for the aza-Michael reaction of 5-substituted tetrazole and α,β-unsaturated carbonyl. The prepared nanocatalyst was fully analyzed by various techniques such as...

Description
Summary:In this paper, diphenyl phosphate creatine was successfully immobilized on Fe 3 O 4 nanoparticles and used as the highly efficient catalyst for the aza-Michael reaction of 5-substituted tetrazole and α,β-unsaturated carbonyl. The prepared nanocatalyst was fully analyzed by various techniques such as Fourier-transform Infrared 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. Graphic abstract This paper discusses a method for the synthesis of substituted tetrazoles via aza-Michael reaction using Fe 3 O 4 @Diphenyl phosphate creatine nanoparticles as a new catalyst.
