eng	Magnetically recoverable catalyst for Henry reaction based on Fe3O4@SiO2 nanoparticles	The preparation and characterization of a heterogeneous recyclable catalyst based on Cu(II) complex of magnetic nanoparticles Fe3O4@SiO2 with (2R,5S)-5-isopropyl-5-methyl-2-(pyridine-2-yl)imidazolidine-4-one was described. Reactions of substituted aldehydes with nitromethane catalyzed by this catalyst provide high conversion (82 – 99%) and high enantioselectivity (73 – 94 % ee).
