摘 要:Scandium-complexed dendritic nanoreactors(SCDNS) on silica,featured with mushroom-like dendrites and deep-falling cavities,were evaluated as catalysts for Friedel-Crafts acylation *** results showed the nanoenvironment of SCDNS played a dominant role in improving the activity of *** fluorobenzene could be acylated smoothly,which hardly occurs in most ***,the catalysts can be easily recovered by simple filtration and reused for several times without significant loss of activity.
