Unprecedented examples of 1-alkyl-1,2,4-triazolium methanesulfonate based Bronsted acidic room temperature ionic liquids were synthesized and characterized. Their catalytic activity and efficiency in recyclability and reusability on one pot synthesis of halide substituted β-amino carbonyl compounds are reported.

A novel recyclable magnetic core–shell nanoparticles Fe3O4@saponin/Cd was synthesized by the combination of nano-Fe3O4@saponin with cadmium acetate. The structure, magnetic features, and morphology of magnetic nanoparticles (MNPs) Fe3O4@saponin/Cd were studied totally via different experiments, such as Fourier transform infrared (FT-IR) spectroscopy, energy-dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), inductively coupled plasma (ICP), high-resolution transmission electron microscopy (HR-TEM), and Brunauer–Emmett–Teller (BET). It was found that the catalyst was active for the synthesis of?β-aminoketone derivatives via one-pot three-component Mannich-type reactions of ketones, aromatic aldehydes, aromatic amines under eco-friendly solvent, at room temperature. Furthermore, this catalyst can be easily recovered magnetically and can be reused for other runs without any reduction in the activity.

A new nano-magnetic core–shell Fe3O4@quillaja sapogenin/Ni (II) was synthesized and characterized thoroughly using various tests including energy-dispersive X-ray spectroscopy (EDS), Brunauer–Emmett–Teller (BET), thermo-gravimetric analysis (TGA), high-resolution transmission electron microscopy (HR-TEM), vibrating sample magnetometer (VSM), Fourier transform infrared (FT-IR) spectroscopy, inductively coupled plasma (ICP), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The achievements demonstrated that the proposed agents were beneficial to synthesis the derivatives of β-aminoketone. Moreover, it was possible to recover the catalyst by means of simple magnetic decantation quickly. Besides, no reduction in the activity of the catalyst occurred, even though it was utilized in various reactions.
