H۲O-DMNPs of β-cyclodextrin modified Fe ۳O۴ were synthesized and used in a Kabachnik -Fields multicomponent reaction for catalysis

Magnetic nanoparticles dispersed in water (H۲O-DMNPs) were synthesized successfully from Fe۳O۴ modified with β-cyclodextrin. Modification with β-cyclodextrin stabilises and controls the structure of Fe۳O۴. The dispersion of Fe۳O۴@β-CD was employed in the Kabachnik-Fields multicomponent reaction, which comprised the synthesis of an amine, aldehyde, and dimethylphosphonate. The rate of phosphonate production was substantially increased by β-CD. Magnetic nanocatalysts have gained significant popularity over the past twenty years as a result of advancements in their functionalization and customization capabilities. Our previous study documented the dispersion and stability of gamma-Fe۳O۴ in ethyl acetate, a compound suitable for catalytic purposes. These materials can be effectively used in catalyzing organic reactions and, in the final stage, can be separated from the reaction mixture with a magnet.
