A highly efficient nano-Fe(3)O(4) encapsulated-silica particles bearing sulfonic acid groups as a solid acid catalyst for synthesis of 1,8-dioxo-octahydroxanthene derivatives
ABSTRACT: The functionalization of silica-coated Fe(3)O(4) magnetic nanoparticles (Fe(3)O(4)@SiO(2)) using chlorosulfonic acid were afforded sulfonic acid-functionalized magnetic Fe(3)O(4) nanoparticles (Fe(3)O(4)@SiO(2)–SO(3)H) that can be applied as an organic–inorganic hybrid heterogeneous cataly...
